C#NET2008 Problem with Two Dimensional Array

[lenniekuah]

Hullo Good Friends,
I need your help again. Please help me.

I am using C#NET2008 to develop application using Two Dimension Array to store String text and INT data.

These are the error messages:
Error #1 Index was outside the bounds of the array.
Error #2 Cannot implicitly convert type 'int' to 'string'

//declare Array variable
private string[ , ] strColmArray = new string[9, 1];

private void FLoadColmArray() {
strColmArray[0, 0] = "Order ID";
strColmArray[0, 1] = “Ord487”; <--- Error #1

strColmArray[1, 0] = “Product ID”;
strColmArray[1,1] = 750.45; - Error #2
}

Error #1 Index was outside the bounds of the array.

You've declared your array to have 9 rows and 1 column, then you are trying to access the second column. You need to declare the array with [9, 2] if you want to access the second column, the one with index 1.

Error #2 Cannot implicitly convert type 'int' to 'string'

That's actually a double (or a float) you're trying to put in there, and this error is because your array is a string. You either need to put quotes around that number, or use a different data type as your storage variable.

If you want to store two different data types in the same array, you'll either need to declare the array as an array of object, or create your own types that use inheritance and have the array be of the base type.

Hopefully that makes sense, please let me know if you have any questions.

Hi Gary,
Thank you very much for sharing information wth me.
I used to develop application using ARRY in VB6 and was surprised that C#NET was different.

Your information has help me to learn new logic. Thank you very much for being generous and helpful in sharing information. You are awesome.
