Built-In Types Table (C# Reference)
Visual Studio 2008
The following table shows the keywords for built-in C# types, which are aliases of predefined types in the System namespace.
All of the types in the table, except object and string, are referred to as simple types.
The C# type keywords and their aliases are interchangeable. For example, you can declare an integer variable by using either of the following declarations:
int x = 123; System.Int32 x = 123;
To display the actual type for any C# type, use the system method GetType(). For example, the following statement displays the system alias that represents the type of myVariable:
Console.WriteLine(myVariable.GetType());
You can also use the typeof operator.
