示例1: Main
//引入命名空间
using System;
using System.Reflection;
using System.Collections.Generic;
// Define a base class with two type parameters.
public class Base<T, U> { }
// Define a derived class. The derived class inherits from a constructed
// class that meets the following criteria:
// (1) Its generic type definition is Base<T, U>.
// (2) It specifies int for the first type parameter.
// (3) For the second type parameter, it uses the same type that is used
// for the type parameter of the derived class.
// Thus, the derived class is a generic type with one type parameter, but
// its base class is an open constructed type with one type argument and
// one type parameter.
public class Derived<V> : Base<int, V> { }
public class Test
{
public static void Main()
{
Console.WriteLine(
"\r\n--- Display a generic type and the open constructed");
Console.WriteLine(" type from which it is derived.");
// Create a Type object representing the generic type definition
// for the Derived type, by omitting the type argument. (For
// types with multiple type parameters, supply the commas but
// omit the type arguments.)
//
Type derivedType = typeof(Derived<>);
DisplayGenericTypeInfo(derivedType);
// Display its open constructed base type.
DisplayGenericTypeInfo(derivedType.BaseType);
}
private static void DisplayGenericTypeInfo(Type t)
{
Console.WriteLine("\r\n{0}", t);
Console.WriteLine("\tIs this a generic type definition? {0}",
t.IsGenericTypeDefinition);
Console.WriteLine("\tIs it a generic type? {0}",
t.IsGenericType);
Console.WriteLine("\tDoes it have unassigned generic parameters? {0}",
t.ContainsGenericParameters);
if (t.IsGenericType)
{
// If this is a generic type, display the type arguments.
//
Type[] typeArguments = t.GetGenericArguments();
Console.WriteLine("\tList type arguments ({0}):",
typeArguments.Length);
foreach (Type tParam in typeArguments)
{
// IsGenericParameter is true only for generic type
// parameters.
//
if (tParam.IsGenericParameter)
{
Console.WriteLine(
"\t\t{0} (unassigned - parameter position {1})",
tParam,
tParam.GenericParameterPosition);
}
else
{
Console.WriteLine("\t\t{0}", tParam);
}
}
}
}
}输出：
--- Display a generic type and the open constructed
type from which it is derived.
Derived`1[V]
Is this a generic type definition? True
Is it a generic type? True
Does it have unassigned generic parameters? True
List type arguments (1):
V (unassigned - parameter position 0)
Base`2[System.Int32,V]
Is this a generic type definition? False
Is it a generic type? True
Does it have unassigned generic parameters? True
List type arguments (2):
System.Int32
V (unassigned - parameter position 0)
