Executing oracle package with recordtype input param throws exception in .NET

I am stuck on an issue for past few days.The issue is detailed below:
There are 15 input params (of type int and varchar), 1 record type param and 5 output params for this oracle package.
It was observed that while passing record type parameter to the package this exception is thrown,work fine with those packages with out record type param.
Exception Thrown:-Unable to cast object of type 'System.Int32' to type

You have this OracleParameter:
OracleParameter P_SO_LINES_TAB_ITEM = new OracleParameter();
P_SO_LINES_TAB_ITEM.ParameterName = "p_so_lines_tab_item";
P_SO_LINES_TAB_ITEM.OracleDbType = OracleDbType.NVarchar2;
P_SO_LINES_TAB_ITEM.CollectionType = OracleCollectionType.PLSQLAssociativeArray;
P_SO_LINES_TAB_ITEM.Size = 1000;
P_SO_LINES_TAB_ITEM.Direction = ParameterDirection.Input;
Value of P_SO_LINES_TAB_ITEM must be a list of plain text (i.e. NVARCHAR2 as you declared by property OracleDbType). However, you try to use a list of OracleParameter objects.
P_SO_LINES_TAB_ITEM.Value = new object[] { QUANTITY, QUANTITY_UOM, ITEM_ID, PROMISE_DATE, SCHEDULE_SHIP_DATE, CURRENCY_CODE, UNIT_SELLING_PRICE, SALESREP_ID };
This is not possible, you cannot make nested parameters.

Got a solution for my problem .We can pass a collection of data by setting the oracle.Dbtype as NVarchar as shown below.
var commandObject = new OracleCommand
{
Connection = con,
CommandText = "Your Packge Name",
CommandType = CommandType.StoredProcedure
};
commandObject.Connection.Open();
commandObject.Parameters.Add("param1", OracleDbType.Int32, ParameterDirection.Input).Value = some int value;
commandObject.Parameters.Add("param2", OracleDbType.Int32, ParameterDirection.Input).Value = some int value;
commandObject.Parameters.Add("param3", OracleDbType.Int32, ParameterDirection.Input).Value = some int value;
commandObject.Parameters.Add("p_xml_type", OracleDbType.NVarchar2, ParameterDirection.Input).Value =some collection
commandObject.Parameters.Add("param returncode", OracleDbType.Varchar2, 200).Direction = "some string value";
commandObject.ExecuteNonQuery();
The collection being set is in xml format of type string and in the oracle package the parameter has been defined as shown below.
p_xml_type IN CLOB

Calling an Oracle insert stored procedure from C#

Stored procedure:
CREATE OR REPLACE PROCEDURE insertMovie(
p_m_id IN MOVIE.M_ID%TYPE,
p_movie_name IN MOVIE.MOVIE_NAME%TYPE,
p_year IN MOVIE.YEAR%TYPE,
p_category IN MOVIE.CATEGORY%TYPE)
IS
BEGIN
INSERT INTO MOVIE ("M_ID", "MOVIE_NAME", "YEAR", "CATEGORY")
VALUES (p_m_id, p_movie_name,p_year, p_category);
END;
/
This is the procedure I have created to insert data into the movie table. Now I am trying to call it from by C#. I have tried the following code but it's not working.
A little help in this regard will be much appreciated. Thank you
private void button1_Click(object sender, EventArgs e)
{
dbConnection conObj = new dbConnection();
OracleConnection theConn = conObj.connFunc();
String p_m_id, p_movie_name, p_year, p_category;
p_m_id = movie_id.Text;
p_movie_name = movie_name.Text;
p_year = year.Text;
p_category = category.Text;
OracleParameter parChoiceIn = new OracleParameter();
OracleParameter parDataIn = new OracleParameter();
OracleParameter parOut = new OracleParameter();
parChoiceIn.ParameterName = "p_m_id";
parChoiceIn.OracleType = OracleType.Number;
parChoiceIn.Size = 32;
parChoiceIn.Direction = System.Data.ParameterDirection.Input;
parChoiceIn.Value = p_m_id;
parDataIn.ParameterName = "p_movie_name";
parDataIn.OracleType = OracleType.VarChar;
parDataIn.Size = 32;
parDataIn.Direction = System.Data.ParameterDirection.Input;
parDataIn.Value = p_movie_name;
parDataIn.ParameterName = "p_year";
parDataIn.OracleType = OracleType.Number;
parDataIn.Size = 32;
parDataIn.Direction = System.Data.ParameterDirection.Input;
parDataIn.Value = p_year;
parDataIn.ParameterName = "p_category";
parDataIn.OracleType = OracleType.VarChar;
parDataIn.Size = 32;
parDataIn.Direction = System.Data.ParameterDirection.Input;
parDataIn.Value = p_category;
OracleCommand cmd = theConn.CreateCommand();
cmd.CommandType = System.Data.CommandType.StoredProcedure;
cmd.CommandText = "insertMovie";
cmd.Parameters.Add(parChoiceIn);
cmd.Parameters.Add(parDataIn);
cmd.Parameters.Add(parOut);
theConn.Open();
OracleDataAdapter adapter = new OracleDataAdapter(cmd);
DataSet myset = new DataSet("theResCur");
adapter.Fill(myset);
theGrid.DataSource = myset;
theGrid.DataSource = myset.Tables[0];
theConn.Close();
}
}

You are creating a parOut parameter but never initializing it.
Also, you are redefining the parDataIn parameter three times, doing so, your OracleCommand only receives the last defined parameter p_category.
I do not understand what is your intent in the last part of your code. If you want to simply call the stored procedure, maybe you should try this:
private void button1_Click(object sender, EventArgs e)
{
dbConnection conObj = new dbConnection();
OracleConnection theConn = conObj.connFunc();
String p_m_id, p_movie_name, p_year, p_category;
p_m_id = movie_id.Text;
p_movie_name = movie_name.Text;
p_year = year.Text;
p_category = category.Text;
theConn.Open();
OracleCommand cmd = theConn.CreateCommand();
cmd.CommandType = System.Data.CommandType.StoredProcedure;
cmd.CommandText = "insertMovie";
cmd.Connection = theConn;
OracleParameter parChoiceIn = new OracleParameter();
OracleParameter parDataIn = new OracleParameter();
parChoiceIn.ParameterName = "p_m_id";
parChoiceIn.OracleType = OracleType.Number;
parChoiceIn.Size = 32;
parChoiceIn.Direction = System.Data.ParameterDirection.Input;
parChoiceIn.Value = p_m_id;
cmd.Parameters.Add(parChoiceIn);
parDataIn.ParameterName = "p_movie_name";
parDataIn.OracleType = OracleType.VarChar;
parDataIn.Size = 32;
parDataIn.Direction = System.Data.ParameterDirection.Input;
parDataIn.Value = p_movie_name;
cmd.Parameters.Add(parDataIn);
parDataIn = new OracleParameter();
parDataIn.ParameterName = "p_year";
parDataIn.OracleType = OracleType.Number;
parDataIn.Size = 32;
parDataIn.Direction = System.Data.ParameterDirection.Input;
parDataIn.Value = p_year;
cmd.Parameters.Add(parDataIn);
parDataIn = new OracleParameter();
parDataIn.ParameterName = "p_category";
parDataIn.OracleType = OracleType.VarChar;
parDataIn.Size = 32;
parDataIn.Direction = System.Data.ParameterDirection.Input;
parDataIn.Value = p_category;
cmd.Parameters.Add(parDataIn);
cmd.ExecuteNonQuery();
theConn.Close();
}

Unable to get Oracle Package function to execute in c#

I'm having difficulty trying to call my DBA's function inside C#. It works fine in the Oracle query browser, however when I attempt to execute it in C# it fails.
The most common error is : "ORA-06502: PL/SQL: numeric or value error: character string buffer too small
ORA-06512: at line 1"
I've attempted to increase the size of the C# parameters but to no success. Not sure what I'm doing wrong.
C# Code :
string returnValue = string.Empty;

using (OracleCommand cmd = new OracleCommand())
{

1st time trying Oracle calls. Never had an issue with SQL. The parameter.Size is commented out for not seeming to do anything.
Was able to get it working by removing the individual Parameters and creating them the Parameter.Add method.
Working Code:
string returnValue = string.Empty;
using (OracleConnection cn = new OracleConnection("ConString"))
{
using (OracleCommand cmd = new OracleCommand())
{
cmd.Connection = cn;
cmd.CommandText = "package.function";
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add("rv", OracleDbType.Varchar2, 200, "", ParameterDirection.ReturnValue);
cmd.Parameters.Add("var1", OracleDbType.Varchar2, 20, "Test808", ParameterDirection.Input);
cmd.Parameters.Add("var2", OracleDbType.Varchar2, 20, "68B54814", ParameterDirection.Input);
cmd.Parameters.Add("var3", OracleDbType.Varchar2, 20, "71839", ParameterDirection.Input);
cmd.Parameters.Add("var4", OracleDbType.Decimal, 55, ParameterDirection.Input);
try
{
cn.Open();
cmd.ExecuteNonQuery();
returnValue = cmd.Parameters["rv"].Value.ToString();
}
catch
{
}
finally
{
cn.Close();
}
}
}
return returnValue;

I fixed this issue by changing its syntax. It was giving numeric or value overflow error if we use below syntax:
cmd.Parameters.Add("strSqlMsg", OracleDbType.Varchar2, 255, ParameterDirection.Output);
Which I changed to below and it worked.
cmd.Parameters.Add("strSqlMsg", OracleDbType.Varchar2, ParameterDirection.Output).Size=255;
Hope this will work for you.
Thanks.

To everybody who is wondering why the answer from Tim B is working.
It's the order of the parameters!
The return parameter of the function has to be bound first!
Also for the other Parameters the order counts and not the name.
The first version with creating the parameters individually, would be OK if "param5" would have been added as first object in to the collection.
I got stuck on this for while :-(

How can I fix this problem?

The objects in the MSFT System.Data namespace relating to Oracle have been deprecated:
http://msdn.microsoft.com/en-us/library/77d8yct7.aspx
But there is a generic System.Data.OleDB namespace:
http://msdn.microsoft.com/en-us/library/system.data.oledb.oledbparameter.direction(v=VS.71).aspx
The Command object has a parameters collection. Each parameter has several properties, including a direction property. When you set that property to output, you can examine its value after issuing the command.
A third-party provider for Oracle should offer something similar.
P.S. I haven't used the OleDB namespace in a very long time -- but recall that the parameters had to be added to the Parameters collection in the same order in which they appear in the SP's signature. Be sure to set the appropriate datatype for each parameter and provide the length of any text values being passed.
P.P.S. It looks as though you're adding the same parameter to the collection twice; is one of these supposed to be commented out?

Oracle .NET error - Wrong number or type of arguments

Now I know this has been asked before. But I've made doubly sure that all parameters are correct and there are no typos. I still get the error. Could somebody please guide me here? I am nearing my wit's end!

Without a specific error that's occuring, its hard to give a specific answer. The code you've posted could be correct. There's nothing I see that is wrong in all scenarios. However, here are a few places I would start looking.
Is your command statement formatted properly? Do all the VarChar parameters accept 1024 characters? Are any of your strings going into a VarChar column longer than 1024? Is the returnStatus type of Int16 correct?
Anyway, those are some places to start, if you post some more detailed information on the issue, you may get some more responses.

I looked at your code and didn't see anything suspicious.
In similar circumstances I'd do a very stupid test: comment out all the parameters except the first one both in the procedure declaration and in the code running it, then test: if there's an error, you'll know that it's with the first parameter; if no error shows, then uncomment the second parameter in the procedure and in the code.
I know it's stupid, time consuming and annoying, but if you really feel you're closed in a corner, this could give you a more precise hint about where the problem is.

DealerID is declared as Number, but passed as string.
I blame the scrollbars, didn't see the Int32.Parse()

No experience with .Net but I wonder if OracleType.Int16 is the correct datatype for the INTEGER parameter (which according to http://msdn.microsoft.com/en-us/library/system.data.oracleclient.oracletype(VS.71).aspx, being a NUMBER, expects a OracleType.Number)?
OracleType.Int16: "This is not a native Oracle data type, but is provided to improve performance when binding input parameters."
