C＃中的UInt32.MaxValue字段(带示例)

UInt32 Struct的MaxValue字段用于表示32位无符号整数的最大值。该字段的值是常数，表示用户无法更改该字段的值。该字段的值为4294967295。其十六进制值为0xFFFFFFFF 。通过在类型转换之前验证Int64值是否在UInt32类型的范围内，可以避免运行时发生OverflowException。

句法：

public const uint MaxValue = 4294967295;

返回值：该字段始终返回4294967295。

例子：

// C# program to illustrate the
// UInt32.MaxValue field
using System;
  
class GFG {
  
    // Main Method
    static public void Main()
    {
        // display the Maximum value
        // of UInt32 struct
        Console.WriteLine("Maximum Value is: " + UInt32.MaxValue);
  
         // Taking an array of the 
        // unsigned long integer 
        // i.e UInt64 data type
        ulong[] num = {3422146, 732443, 42343535776, 2342534654756123};
  
        // taking variable of UInt32 type
        uint mynum;
  
        foreach(long n in num)
        {
  
            if (n >= UInt32.MinValue && n <= UInt32.MaxValue) 
            {
  
                // using the method of Convert class
                // to convert Int64 to UInt32
                mynum = Convert.ToUInt32(n);
  
                Console.WriteLine("Conversion is Possible.");
            }
  
            else
            {
                Console.WriteLine("Not Possible");
            }
        }
    }
}

输出：

Maximum Value is: 4294967295
Conversion is Possible.
Conversion is Possible.
Not Possible
Not Possible
