Dim vaResultSet

If Not IsArray(vaResultSet) Then

ReDim vaResultSet(0)

Else

ReDim Preserve vaResultSet(UBound(vaResultSet) + 1)

End If

Thanks in advance

It's pretty much difficult to convert this into C# code, but let me try and see how it goes.

I'm not too sure what you're doing here, but maybe it's something like this.

Object vaResultSet = new Object();

This can be done using something like this.

Type at = typeof(vaResultSet);
if (!at.IsArray) {

ReDim vaResultSet(0)

This is somewhat interesting. ReDim resizes the object to an array of 0. It's pretty difficult to do this unless vaResultSet has been declared an array first. I would suggest that the 1st line when declaring vaResultSet be an array instead. Or assign it to another variable and return the array instead. So I would do something like this.

Before the if-else statement, I'll declare an array variable first.

Object[] myArray;

Then for the ReDim itself,

myArray = new Object[1];

myArray[0] = vaResultSet;

Else ReDim Preserve vaResultSet(UBound(vaResultSet) + 1)

This is also pretty interesting to do. In C# you won't be able to resize the object, so you'll have to create another new object to do so.

myObject = new Object(varResultSet.Length) + 1);
Array.Copy(myObject, varResultSet, varResultSet.Length);

that should do the trick. You can replace Object with any type u require. I'm just assuming here.

Use this: http://www.carlosag.net/Tools/CodeTranslator/Default.aspx and you will get this:

object vaResultSet;
if (!IsArray(vaResultSet)) {
    object vaResultSet;
}
else {
    object Preserve;
    vaResultSet((UBound(vaResultSet) + 1));
}

Hi plsaiuser,

Even though it is not equivalent(identical) translation, it will be better if you can rewrite the coding by using ArrayList.

the conversion is wrong, isn't it?

Thanks for your info
