Int32 Struct的MaxValue字段或属性用于表示Int32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2147483647 。它的十六进制值为0x7FFFFFFF 。它用于避免在转换为Int32值时发生OverflowException。
句法：
public const int MaxValue = 2147483647;返回值：该字段始终返回2147483647。
例子：
// C# program to illustrate the
// Int32.MaxValue field
using System;
class GFG {
// Main Method
static public void Main()
{
// display the Maximum value
// of Int32 struct
Console.WriteLine("Maximum Value is: "+
Int32.MaxValue);
// Taking an array of long i.e Int64 data type
long[]num = {347, 49458, 345348534650436656};
// taking variable of Int32 type
int mynum;
foreach(long n in num){
if(n >= Int32.MinValue && n <= Int32.MaxValue)
{
// using the method of Convert class
mynum = Convert.ToInt32(n);
Console.WriteLine("Conversion is Possible.");
}
else
{
Console.WriteLine("Not Possible");
}
}
}
}
输出：
Maximum Value is: 2147483647
Conversion is Possible.
Conversion is Possible.
Not Possible
