String.Replace Not working in VB.NET 2005 | Tech Off

Shark_M

Hi guys,
The String.Replace (String1, string2) does not seem to be working.
I dont know why, but there might be some bug with it

Try something like this

Dim StrX as string = "@Testing"
now Dim StrY as string = StrX.Replace ("@", String.Empty)

This will not work in my project, i dont know why

So i am forced to use the old function called Replace

so i say StrY = Replace (StrX,"@",String.Empty)

So why is the first one not working in VB.NET 2005?

Not sure what your problem is... the following works fine for me:

        Dim StrX As String = "@Testing"
        Dim StrY As String = StrX.Replace("@", String.Empty)
        System.Console.WriteLine(StrY)

The output is: "Testing"

I did the same in C# and it all worked fine. You may want to make sure you're running the 2.0 framework? Other than that, no clue.

I did the same thing in C# and it works fine. But not in VB.net, it goes through it as if the "@" does not exist in the string, and outputting "@Testing". I dont know why its not working. SO for now i am using the old one from vb6, Replace (String, ReplacementString1, withString2)

I find Visual Studio 2005 VB.NET buggy, its like a beta3 more than a RTM

My name has 9 letters. Coincidence? I think not...

I works fine here, in VB as well as C#, on .Net 2.0 RTM.

I will reinstall VS2005 again. I recently installed a HotFix for VS2005, that addesses VB Compiler bug, maybe that what did it? I will check and see

We can make it better, stronger, faster.

Same result here, unfortunately. This works fine:

Dim foo As String = "@Testing"

Dim Bar As String = foo.Replace("@", String.Empty)

System.Console.WriteLine(Bar)

What MSIL is the compiler generating?

If you are testing StringX for a change there will be none. StringY will have been changed though.

string StringX = "@Replace";
string StringY = StringX.Replace("@", string.Empty);
Console.WriteLine(StringX); //Results in @Replace
Console.WriteLine(StringY); //Results in Replace

If it s not a VB.NET problem. As string class is the same accross either language. My bet is some place you are calling stringX during output when you should be calling StringY.

You can always do the replace to StringX if this is the case:
//C#:
StringX = StringX.Replace("@", string.Empty);
//VB.NET:
StringX = StringX.Replace("@", string.Empty)

I have used Replace scads of times. When I first learned of it I made the assignment error too. Assuming it would assign to itself. Being immutable the opposite makes total sense. Also being able to control where the result is stored makes a lot of sense.

This does not work for me either.

I am using VS 2003 with .NET 1.1

I think its something to do with the "@" character, b/c mine is not working and I am trying to replace "{"s and "}"s.

if( !succeed( try() ) ) { while(true) try(); }

It's nothing to do with what's in the string. It's to do with how string.replace works.

String String.Replace(String replaceString, String replaceWith)

This function does NOT change the string that calls the method - but instead returns a new string with the result:

String a = "@Testing";
String b = a.Replace("@", "blab");

// a == "@Testing", b == "blabtesting".

Human after all

I know this is an old thread, and that people have to learn.. but this is still pretty funny Tongue Out

In a 'shouldn't laugh but.. aw come on!' kinda way..

Dead give away about misunderstood mutability of strings in .net (or rather lack of) comes from the vbscript'esq global method 'Replace' vs the strings method..
