// Alternatively, you could use
// SampleClass obj = new SampleClass();
// Type t = obj.GetType();

}出力
Methods:
Void SampleMethod()
System.Type GetType()
System.String ToString()
Boolean Equals(System.Object)
Int32 GetHashCode()
Members:
Void SampleMethod()
System.Type GetType()
System.String ToString()
Boolean Equals(System.Object)
Int32 GetHashCode()
Void .ctor()
Int32 sampleMember
次の例では、GetType メソッドを使用して、数値計算の結果の格納に使用する型が決定されます。これは、結果として導かれた数値のストレージ要件によって異なります。
// cs_operator_typeof2.cs
using System;
class GetTypeTest
{
static void Main()
{
int radius = 3;
Console.WriteLine("Area = {0}", radius * radius * Math.PI);
Console.WriteLine("The type is {0}",
(radius * radius * Math.PI).GetType()
);
}
}出力
Area = 28.2743338823081
The type is System.Double
