C# .NET - Where is the definition for GetType() function ?

Once we create an object for user defined class, We could see some methods like "getType()","toString()","getHashCode".. are getting defined by default.

1.     Where are they defined ?
2.     When are they getting defined?

those methods all derive from Object if I am not mistaken.

thanks for reply,

Nomally , A method will be available for an object if we have defined that method in our class .But  I have't defined any methods like "getType()"

You can find the defenition of all methods and properties on MSDN:

You need to add the assembly name in for any type that is not in the corrent assembly or mscorlib.

So Type t = Type.GetType("System.Data.DataTable, System.Data, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089");

will work (for version 1.1 of the framework - if you're using 1.0 use the version number for that one)

Btw: System.String is not a Value Type, it a Reference Type.

Hope it helps.
