hi, is there a build in function for UBOUND in c#? I am trying to convert from ASP to ASP.NET (C#) ... Any suggestion?? Thanks in advance.

check the length property...

I sincerely hope you're not trying to mirror line for line between asp and asp.net.  That's an easy way to get stuck in a royal pain.

I don't know much about ASP, but I know there is a UBound function in the Microsoft.VisualBasic namespace.

Microsoft.VisualBasic.Information.UBound()

Does anyone have a solution for this? I'm having the same problem here. I converted the following piece of code using a conversion tool called Instrant C#, but I'm getting an error:

From VB.NET:

For i = 0 To UBound(localCart, 2)
 If CStr(localCart(CARTID, i)) <> "" Then
  orderTotal = orderTotal + (CDbl(localCart(CARTPPRICE, i)) * CDbl(localCart(CARTPQUANTITY, i)))
'do something
 End If
Next

To C#:
int tempFor1 = localCart.GetUpperBound(1);
for (i = 0; i <= tempFor1; i++)
{
 if (System.Convert.ToString(localCart(CARTID, i)) != "")
 {
  orderTotal = orderTotal + (System.Convert.ToDouble(localCart(CARTPPRICE, i)) * System.Convert.ToDouble(localCart(CARTPQUANTITY, i)));
//do something 
 }
}

The error message: 
Compiler Error Message: CS0117: 'object' does not contain a definition for 'GetUpperBound'

I'm using ASP.NET 1.1. Please help!

Have you tried Microsoft.VisualBasic.Information.UBound()?

Change the declaration of "localCart" to be an array and the problem will go away.

As I mentioned in the other group, Instant C# can't get into the type inference game that the VB compiler performs when you don't type your variables.

Hi,

Are you talking about the UBOUND of vbscript's array?

maybe you can use the GetUpperBound() in C#....

e.g.:

string[] myArray = new string[2];
myArray.GetUpperBound(0);

Stop the madness!

Use the length property of the array, thats what it exists for.

Yes - 'Length' is certainly the one to normally use - but for conversion purposes 'GetUpperBound' is the equivalent of VB's 'UBound' (since UBound does not equal length, and when you deal with multi-dimensional arrays, GetUpperBound is more useful).

But in this example, using 'Length' won't work either until the variable is declared as an array (VB really lets you get away with some very sloppy coding).

QFT!!!! Listen to the prophet!

(fyi: collections have Count instead.)

Infernal conversion! ;)

C#  ain't scripting language ;) strong types are required.

To get solid conversion, you should probably use the length and include some Debug.Asserts.

With each array LBound or UBound you convert to use length, you will want to assert that the lower bound (with the method mentioned) is zero and the the upper bound is equal to the length.

If those assertions don't pass, then the array you are using is likely to cause issues in other places. When the conversion is compete and fully validated, you can remove the asserts

Thanks guys. arrVals.GetUpperBound(0) solved the problem.

arrVals.Length gave this error:

System.IndexOutOfRangeException: Index was outside the bounds of the array.

u can either include a reference to Microsoft.VisualBasic and use array.UpperBound(int i), where i is the value to want to check for

or use array.length and check for the value(i + 1)

Use 0 to yourArray.Items.Count()

 something like

for (int c=0; c< yourArray.Items.Count(); c++)

{ };
