小数。C# 中的 ToUInt32()方法
原文:https://www . geesforgeks . org/decimal-touint 32-method-in-c-sharp/
此方法用于将指定的十进制值转换为等效的 32 位无符号整数。用户还可以使用显式赋值运算符将十进制值转换为 32 位无符号整数。
语法:公共静态 uint ToUInt32(十进制 d);
这里 d 是要转换的十进制数。
返回值:返回一个 32 位无符号整数,相当于指定的 d 。
异常:如果 d 为负或大于最大值,该方法将给出飞越异常。
以下程序说明了上述方法的使用:
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);
}
}
}
Output:
The UInt32 value is : 2147483647
The UInt32 value is : 4294967295
例 2: 适用于飞越异常
// 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);
}
}
}
Output:
Exception Thrown: System.OverflowException
