此方法用于将指定的Decimal的值转换为等效的32位无符号整数。用户还可以使用Explicit赋值运算符将Decimal值转换为32位无符号整数。

下面的程序说明了上述方法的用法:

范例1:

// C# program to demonstrate the
// Decimal.ToUInt32(Decimal) Method
using System;
  
class GFG {
  
    // Main Method
    public static void Main()
    {
        try {
  
            // Taking decimal variables
            Decimal dec1 = 2147483647M;
            Decimal dec2 = 4294967295.784m;
  
            // using Decimal.ToUInt32(Decimal) Method
            uint val1 = Decimal.ToUInt32(dec1);
  
            // using Decimal.ToUInt32(Decimal) Method
            uint val2 = Decimal.ToUInt32(dec2);
  
            // Printing the UInt32 value
            Console.WriteLine("The UInt32 value "
                             + "is : {0}", val1);
                               
            // Printing the UInt32 value
            Console.WriteLine("The UInt32 value "
                              + "is : {0}",val2);                              
        }
  
        catch (OverflowException e) {
            Console.Write("Exception Thrown: ");
            Console.Write("{0}", e.GetType(), e.Message);
        }
    }
}
输出:
The UInt32 value is : 2147483647
The UInt32 value is : 4294967295

示例2:对于OverflowException

// C# program to demonstrate the
// Decimal.ToUInt32(Decimal) Method
using System;
  
class GFG {
  
    // Main Method
    public static void Main()
    {
        try {
  
            // Taking the maximum value
            // of Decimal
            Decimal dec1 = Decimal.MaxValue;
  
            // using Decimal.ToUInt32(Decimal) Method
            // It will give error as decimal number
            // is above the range of UInt32
            uint val1 = Decimal.ToUInt32(dec1);
  
            // Printing the UInt32 value
            Console.WriteLine("The UInt32 value "
                             + "is : {0}", val1);                             
        }
  
        catch (OverflowException e) {
            Console.Write("Exception Thrown: ");
            Console.Write("{0}", e.GetType(), e.Message);
        }
    }
}
输出:
Exception Thrown: System.OverflowException
