I have created a multidimensional array.I wants to display it in the .aspx page. please help.my code is here.It doesnt shows the array values
string[,] array_questions = new string[dt.Rows.Count, dt.Columns.Count];
for (i = 0; i < dt.Rows.Count; i++)
{
for (j = 0; j < dt.Columns.Count; j++)
{
array_questions[i, j] = dt.Rows[i][j].ToString();
//TextBox1.Text = array_questions[i,j];
}
}
Console.Write(array_questions[i, j] + " ");
you can also use Response.write
Console.Write is used for console applications.
If you want to display the data on the aspx webpage you need to create a webcontrol (for example label) and set its text property with an appropriate value.
If you want to write the values in the table in the console visual studio, call the method
Console.Out.Write() and not Console.Write().
Otherwise call Response.Write() to write on the page
// display the array
for (int i = 0; i < array_questions.GetLength(0); i++)
{
for (int j = 0; j < array_questions.GetLength(1); j++)
{
Response.Write("i="+i+" "+"j="+j);
Response.Write("<br>");
}
}

I am loading csv file values in array and want to create a chart.
for(int i = 0; i < array.GetLength(1); i++)
{
int x = sum[i];
chart1.Series.Add(array[0, i]);
chart1.Series[array[0, i]].Points.AddXY(i, x.ToString());
}
only last bar is showing as output correctly.
here is csv file snapshot.
enter image description here
when i tried with hardcoded values like
chart1.Series["S1"].Points.AddXY(1.ToString(), 99);
chart1.Series["S1"].Points.AddXY(2.ToString(), 88);
chart1.Series["S1"].Points.AddXY(3.ToString(), 33);
it was showing correct output as shown in snapshot.
hardcoded values
Try something like the syntax used here for a bar chart. There is also an update to your sum function, since I don't know other ways to sum the columns of a 2D array.
for(int i = 0; i < array.GetLength(1); i++)
{
int x = 0;
for (int j = 1; j < array.GetLength(1); j++) {
x += array[j, i]
}
chart1.Series.Add(array[0, i]);
chart1.Points.AddXY(array[0, i], x);
}
I am trying to clone the game "Minesweeper" in c#.
When I create a field, I want the background of the button control to be the same as in the original game "Minesweeper".
However, when I create my field and I add all the images it takes at least 1-5 seconds to completely load the field.
Code for creating the field:
for (int i = 0; i < fieldsize; i++)
{
for (int j = 0; j < fieldsize; j++)
{
panel1.controls.add(new Button(){backgroundimage = properties.resources.field})
}
}
Any help is appreciated!
I have a little challenge that I can't get around. I have a result from the code below.
if (Request.Cookies["ProductRecord"] != null)
{
s = Convert.ToString(Request.Cookies["ProductRecord"].Value);
string[] strArr = s.Split('|');
for (int i = 0; i < strArr.Length; i++)
{
t = Convert.ToString(strArr[i].ToString());
string[] strArr1 = t.Split(',');
for (int j = 0; j < strArr1.Length; j++)
{
a[j] = strArr1[j].ToString();
}
SingleCount = (Convert.ToDecimal(a[1].ToString()) * Convert.ToDecimal(a[3].ToString()));
}
}
How do I bind the results of SingleCount to a label inside a repeater.
RepeaterId.DataSource = SingleCount is the closest i have thought of but its not working.
I'm making some assumptions based upon your code so I may be off-base on what you're trying to achieve, but couldn't you take SingleCount and add it to a list of decimals and then bind that list to the DataSource of your repeater?
I have a litte problem here. I have a two-dimensional array which is [5,5] big.
I have a windows form with 25 buttons. Now I want to store the buttons in the object array, but my problem is, how do I tell the program to know which button to put in the array? Is it possible in some kind of this way:
//_array[i] = button(i);
This is my first time storing objects in an array and I dont know how to do that.
EDIT: The buttons have all the standard names (button1,button,button3...)
EDIT2: I know how to it by hand (_array[x,y] = button1) but I want to know how to it ith a for-loop.
You could filter the controls by using IEnumerable.OfType():
//get all buttons and order them by name
var buttons = Controls.OfType<Button>().OrderBy(x => x.Name).ToList();
for(int i = 0; i < 5; i++)
for(int j = 0; j < 5; j++)
_array[i, j] = buttons[i*5+j];
You can access the buttons using their name as index of the Controls collection:
for (int i = 0; i < 5; i++) {
for (int k = 0; k < 5; k++) {
_array[i, k] = Controls["Button" + (5 * i + k + 1).ToString()];
}
}
Try this:
for (int i=0; i<5; i++)
for (int j=0; j<5; j++)
_array[i,j] = Controls.Item["Button" + (i*5 +j).ToString()];
I have a simple 2D array:
int[,] m = { {0,0,0,0,0,0,0,0,0,0}, {0,0,0,0,0,0,0,0,0,0} };
How can I print this out onto a text file or something? I want to print the entire array onto a file, not just the contents. For example, I don't want a bunch of zeroes all in a row: I want to see the
{{0,0,0,0,0,0,0,0,0,0}, {0,0,0,0,0,0,0,0,0,0} };
in it.
Just iterate over it and produce the output. Something like
static string ArrayToString<T>(T[,] array)
{
StringBuilder builder = new StringBuilder("{");
for (int i = 0; i < array.GetLength(0); i++)
{
if (i != 0) builder.Append(",");
builder.Append("{");
for (int j = 0; j < array.GetLength(1); j++)
{
if (j != 0) builder.Append(",");
builder.Append(array[i, j]);
}
builder.Append("}");
}
builder.Append("}");
return builder.ToString();
}
There is no standard way to get those { brackets, you have to put them through the code while iterating through your array and writing them to the file
