C# Convert.GetTypeCode(Object)用法及代码示例

此方法用于返回指定对象的TypeCode。

用法:

public static TypeCode GetTypeCode (object value);

在这里，该值是一个实现IConvertible接口的对象。

返回值：此方法返回值的TypeCode，如果value为null，则返回Empty。

以下示例程序旨在说明Convert.GetTypeCode(Object)方法的用法：

示例1:

// C# program to demonstrate 
// Convert.GetTypeCode() Method 
using System; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
  
        // Declaring val1 and val2 
        string val1; 
        bool val2; 
  
        // intializing the 
        // val1 and val2 
        val1 = "abab"; 
        val2 = true; 
  
        // getting TypeCode 
        // using Convert.GetTypeCode() method 
        TypeCode t1 = Convert.GetTypeCode(val1); 
        TypeCode t2 = Convert.GetTypeCode(val2); 
  
        // Display TypeCode 
        Console.WriteLine("TypeCode of val1 is {0}", t1); 
        Console.WriteLine("TypeCode of val2 is {0}", t2); 
    } 
}

输出：

TypeCode of val1 is String
TypeCode of val2 is Boolean

示例2:

// C# program to demonstrate 
// Convert.GetTypeCode() Method 
using System; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
  
        // Declaring val1 and val2 
        char val1; 
        float val2; 
  
        // intializing the 
        // val1 and val2 
        val1 = 'a'; 
        val2 = 20f; 
  
        // calling get() method 
        get(val1); 
        get(val2); 
    } 
  
    // Defining the get() method 
    public static void get(char val) 
    { 
  
        // getting TypeCode 
        // using Convert.GetTypeCode() method 
        TypeCode t = Convert.GetTypeCode(val); 
  
        // Display the TypeCode 
        Console.WriteLine("TypeCode of {0}"+ 
                         " is {1}", val, t); 
    } 
    public static void get(float val) 
    { 
  
        // getting TypeCode 
        // using GetTypeCode() method 
        TypeCode t = Convert.GetTypeCode(val); 
  
        // Display the TypeCode 
        Console.WriteLine("TypeCode of {0}"+ 
                         " is {1}", val, t); 
    } 
}

输出：

TypeCode of a is Char
TypeCode of 20 is Single
