I have a code like this
string[] data = new string[] { "1", "2", "3", "4", "5", "6", "7", "8",
"9", "10", "11", "12", "13", "14",
"1", "2", "3", "4", "5", "6", "7", "8",
"9", "10", "11", "12", "13", "14",
"1", "2", "3", "4", "5", "6", "7", "8",
"9", "10", "11", "12", "13", "14",
"1", "2", "3", "4", "5", "6", "7", "8",
"9", "10", "11", "12", "13", "14",
"1", "2", "3", "4", "5", "6", "7", "8",
"1", "2", "3", "4", "5", "6", "7", "8",
"9", "10", "11", "12", "13", "14",
"9", "10", "11", "12", "13", "14",};
using (PdfWriter writer = new PdfWriter(destinationFile))
{
// Creating a PdfDocument object
using (PdfDocument pdfDoc = new PdfDocument(writer))
{
// Creating a Document object
using (Document doc = new Document(pdfDoc))
{
// Creating a table
float[] pointColumnWidths1 = { 150f, 150f, 150f, 150f };
Table table = new Table(pointColumnWidths1);
Cell cell;
float[] pointColumnWidths2 = { 150f };
Table nestedTable = new Table(pointColumnWidths2);
for (int y = 0; y < data.Length; y++)
{
cell = new Cell();
cell.Add(data[y]);
nestedTable.AddCell(cell);
}
table.AddCell(nestedTable);
doc.Add(table);
doc.Close();
}
}
}
And this is the output
What am i doing is Populating a four table column using itext not itextsharp.
Ok the nested table is working so far. But if the data array is populated up to 100 string of array. I'm receiving an error
System.ArgumentOutOfRangeException: 'Index was out of range. Must be non-negative and less than the size of the collection.
And i assume that the error is because the populated nested table is too big for the parent table?
So how can i make it adjust that if the nested table is too big. some of the data will be written on the next column. I can't really solve the problem my self so i'm asking a question here.
Sorry for the incomplete question.
Here is the error
Index was out of range. Must be non-negative and less than the size of the collection.

Thank you very much
I assume you use an older iText7 version (probably a 7.0.x?) because you use
string[] data = ...;
...
cell.Add(data[y]);
while Cell.Add(string) has been removed from the iText7 API nearly 2 years ago.
To make your code runnable with a current iText7, I replaced that Add call by
cell.Add(new Paragraph(data[y]));
After this simple replacement, your code ran without issue with a current iText 7.1.7 SNAPSHOT and with the 7.1.6 release.
Indeed, a lot of work has been done in particular in the table creation code. Thus, you appear to have run into a meanwhile fixed table related bug.
To continue you should update.

I am using for each to iterate and get values of a json object in my solution.
Let me give example of the json.
[
{
"#Seq": "1",
"#text": "123456789"
},
{
"#Seq": "2",
"#text": "abc"
},
{
"#Seq": "3",
"#text": "xyz"
}
]
It works well for multiple sequences until we have only one seq in the json.
example:
{{
"#Seq": "1",
"#text": "123456789"
}}
Coming to Code:
foreach (var installinst in atpmessage["AUTOPILOTMessage"]["AUTOPILOTBody"]["OrderHeader"]["InstallationInstructions"]["InstallationInstruction"])
{
responseISGEMEA.data.install_instruct =installinst["#text"].ToString();
}
The installinst in the loop gives me just the Seq. Not the text.
{"#Seq": "1"}
how do I make it work with single and multiple sequences.
We have a json object provided by vendor with naming conventions suitable only for vendor system. We would like to rename all the json attributes names matching our company's naming standards. I showed a very small XML file but in reality we have a huge XML with many elements. The transformed json object will eventually be persisted in our datastore.Any inputs in handling efficient way?

I have a little problem converting my JSON Object I have to something I can work within C# code.
{ "CheckboxHours": {
"method": "ID",
"valueparts": [
"Hour",
[ "0", "1", "2", "3", "4", "5", "6", "7", "8", "9", "10", "11", "12", "13", "14", "15", "16", "17", "18", "19", "20", "21", "22", "23" ]
]
}
}
This is my JSON String I have, which is for creates me the Selenium Object.
What i want is to combine the values from valueparts[0] ("Hour") with valueparts[1][0-23] with each other and create an array of Selenium Objects
var jsonData = JsonConvert.DeserializeObject<jsonc#file>(_jsonFile);
Object[] hours = (Object[])jsonData.CheckboxHours.Valueparts[1];
SeleniumCheckBox[] checkbox = new SeleniumCheckBox[hours.Length];
for (int i = 0; i < hours.Length; ++i)
{
cbHour[i] = new SeleniumCheckBox(jsonData.CheckboxHours.Valueparts[0].ToString() + hours[i]);
}
The SeleniumCheckBox is a Class I made which just takes the value and creates in the background a new Selenium Element with findElement(By.ID(value)). This is working already.
My Problem here is that he doesn't allow the Conversion from jsonData to Object[] and I don't really know how I can handle this.
I hope it is clear what I want to have - if not feel free to ask for more specific data.
I think. You can try this.
var jsonData = JsonConvert.DeserializeObject<dynamic>(_jsonFile);
var hours = jsonData.CheckboxHours.valueparts[1];
foreach (var hour in hours)
{
//Some code
}
I am not sure if I understood everything correctly, but the reason for failure in deserialization might be that valueparts is List parameter, usually in c# the Lists contain only 1 type of parameters eg. string, or int. In your case, "Hour" (valueparts[0]) is a string, and valueparts[1] is List. I assume here is the conflict with deserializing the JSON string.
{
CheckboxHours:{
"method":"ID",
"valueparts":{
Measure: "Hour",
MesureValues:
[
"0","1","2","3","4","5","6","7",
"8","9","10","11","12","13","14",
"15","16","17","18","19","20",
"21","22","23"
]
}
}
}
Change valueparts to object, as in the code above, so you can use Hour as string and the values as List.
i have string array as the following
string[] strArray = new string[] { "1", "2", "3", "5", "6" };
the question is
how can i add item to this created Array at specific position
to be like
{ "1", "2", "3" , "4" , "5", "6" }
i need some thing can append value at specific index and keep the old values
You can't do this, since arrays have fixed length after creation. Use List<string> instead (which internally stores its items in array):
var strList = new List<string> { "1", "2", "3", "5", "6" };
strList.Insert(2, "foo");
If you'll need to convert the list into array, use ToArray extension method:
var strArray = strList.ToArray();
Arrays are immutable, but Lists are not:
var list = strArray.ToList();
list.Add("6")
strArray = list.ToArray();
Or, at a specific index:
var list = strArray.ToList();
list.Insert(3, "4");
strArray = list.ToArray();
I have two arrays say
var list1 = string[] {"1", "2", "3", "4", "", ""};
var list2 = string[] {"2", "3", "4","",""};
When i try to get common items form these two array using following code
var listCommon = list1.Intersect(list2);
It gives me result like this
string[] {"2", "3", "4", ""}
But i want it should return like this
string[] {"2", "3", "4", "", ""}
It is escaping last empty string value while intersecting.
Set methods like Intersect or Except remove duplicates from each collection. I assume you want something like this instead:
var listCommon = list1.Where(list2.Contains);
which is not as efficient. This could be an optimization:
var l2Lookup = new HashSet<string>(list2);
var listCommon = list1.Where(l2Lookup.Contains);
This will work:
list1.Where(x=>list2.Contains(x))
