How can I define type variant in c#?

 

[bruce barker]

use datatype object. you can use the is operator to determine type

void mtProc(object obj)
{
if (obj is int)
...
else if (obj is string)
...
else if (obj is myDatatype)
....
}

to call any methods other than the object generic, you will need to use a
cast.

note: if you are call calling a com routine, object is also the type that is
used for a variant parameter (or return value)

Thanks. What should I do if I do not know the return type of a class/function
of a certain thirdparty library?

In VB I can say

variant abcd=MyThirdPartyLib.MyThirdPartyLibFunction()

What would be the equivalent in C#?

The .NET Framework does not have a "variant" type. If you start typing the
method signature of a referenced third-party library in the Visual Studio
IDE, Visual Studio Intellisense will show you the return type of the method.

Failing that, you can do this:

Object abcd=MyThirdPartyLib.MyThirdPartyLibFunction();

type t = typeof(abcd);

That will do it.

Thanks a lot.
