Convert Delphi to C#

[Kostya Ergin]

hi, i am very new in C#.

How to do this in C#:

This is function:
function test(param: string): string;
begin
end;

I can get result of "test" function:
result := test(param);


And how to do in C# ?

Kostya,

I've never used Delphi, but it looks like you would use:

string test(string param)
{
return null;
}

There is a "return null" in there because you need to return something.
Also, I don't know what the default is for passing parameters in Delphi (is
param passed by value, or by reference?), but the C# code is passing the
string reference by value.

Hope this helps.

I'm not entirely sure what you were trying to say - Nicholas was
exactly correct, the string reference is passed by value.

The closest you can get to a Delphi function in C# would be a non-void
static method:

static string test(string param) {
// this won't compile since this method is non-void and no value is
// returned, and that's not valid C#
}

FWIW, C# static methods are pretty much the same as Delphi class methods.
Therefore, the above is pretty much the same as:

class function InsertClassName Here.test(param : string): string;
begin
end;
