UInt32。C# 中的最大值字段，示例
原文:https://www . geesforgeks . org/uint 32-max value-field-in-c-sharp-with-examples/
UInt32 Struct 的 MaxValue 字段用于表示 32 位无符号整数的最大值。该字段的值为常量意味着用户不能更改该字段的值。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一个 Int64 值是否在 UInt32 类型的范围内，来避免运行时出现溢出异常。
语法:
public const uint MaxValue = 4294967295;
返回值:该字段始终返回 4294967295。
示例:
// 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
