Translating C++.Net code to C# - {RESOLVED}

[wossname]

I've seen the light, I've given up C++.net and as a result, I've got a large chunk of code to trawl through to move over to C#.

One thing though, In C++ I used this to test whether a pointer had been initialised...

if(!pMyString)
//it hasn't been initialised yet
else
//it has

In C# I have changed the pointer into to a string variable.

Now if I have:

string MyString;
//...

what is it's state now, it is null, nothing, empty, "" or what?

And how do I test it.

Thanks.

PS, why didn't anyone tell me that Managed C++ was so arse?

Not one hundred percent:
mystring != null

[dynamic_sysop]

when initially creating the string, try this...

[Color=Blue]string[/color] MyString = [Color=Blue]string[/color].Empty;

then you can check if the string is empty or not like this....

[Color=Blue]private[/color] [Color=Blue]void[/color] button1_Click([Color=Blue]object[/color] sender, System.EventArgs e)
        {
            [Color=Blue]string[/color] MyString = [Color=Blue]string[/color].Empty;
            [Color=Blue]if[/color](MyString==[Color=Blue]string[/color].Empty)
            {
                 MessageBox.Show("it's empty");
            }
            [Color=Blue]else
[/color]           {
                 MessageBox.Show("it's NOT empty");
            }
        }

That'll do it.

i do believe it is null if you dont assign nothing to it, wouldnt it be if it was with any other object type?
