C# Type.GetInterfaces()用法及代碼示例

Type.GetInterfaces()方法用於在派生類中重寫時，獲取由當前Type實現或繼承的所有接口。

用法： public abstract Type[] GetInterfaces ();

返回值：此方法返回一個Type對象數組，表示由當前Type實現或繼承的所有接口；如果當前Type沒有實現或繼承任何接口，則返回一個Type類型的空數組。

以下示例程序旨在說明Type.GetInterfaces()方法的使用：

示例1:

// C# program to demonstrate the 
// Type.GetInterfaces() Method 
using System; 
using System.Globalization; 
using System.Reflection; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        // Declaring and intializing object of Type 
        Type objType = typeof(int); 
  
        // Getting interface of specified name 
        // using GetField(String) Method 
        Type[] minterface = objType.GetInterfaces(); 
  
        // Display the Result 
        Console.WriteLine("Interface present in type {0}", objType); 
        for (int i = 0; i < minterface.Length; i++) 
            Console.WriteLine(" {0}", minterface[i]); 
    } 
}

輸出：

Interface present in type System.Int32
 System.IFormattable
 System.IComparable
 System.IComparable`1[System.Int32]
 System.IConvertible
 System.IEquatable`1[System.Int32]

示例2:如果沒有定義公共領域

// C# program to demonstrate the 
// Type.GetInterfaces() Method 
using System; 
using System.Globalization; 
using System.Reflection; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        // Declaring and intializing object of Type 
        Type objType = typeof(string); 
  
        // Getting interface of specified name 
        // using GetField(String) Method 
        Type[] minterface = objType.GetInterfaces(); 
  
        // Display the Result 
        Console.WriteLine("Interface present in type {0}", objType); 
        for (int i = 0; i < minterface.Length; i++) 
            Console.WriteLine(" {0}", minterface[i]); 
    } 
}

輸出：

Interface present in type System.String
 System.ICloneable
 System.Collections.Generic.IEnumerable`1[System.Char]
 System.IComparable
 System.IComparable`1[System.String]
 System.IConvertible
 System.Collections.IEnumerable
 System.IEquatable`1[System.String]
