示例1: Main
// This example demonstrates Math.Sign()
using System;
class Sample
{
public static void Main()
{
string str = "{0}: {1,3} is {2} zero.";
string nl = Environment.NewLine;
byte xByte1 = 0;
short xShort1 = -2;
int xInt1 = -3;
long xLong1 = -4;
float xSingle1 = 0.0f;
double xDouble1 = 6.0;
Decimal xDecimal1 = -7m;
// The following type is not CLS-compliant.
sbyte xSbyte1 = -101;
Console.WriteLine($"{nl}Test the sign of the following types of values:");
Console.WriteLine(str, "Byte ", xByte1, Test(Math.Sign(xByte1)));
Console.WriteLine(str, "Int16 ", xShort1, Test(Math.Sign(xShort1)));
Console.WriteLine(str, "Int32 ", xInt1, Test(Math.Sign(xInt1)));
Console.WriteLine(str, "Int64 ", xLong1, Test(Math.Sign(xLong1)));
Console.WriteLine(str, "Single ", xSingle1, Test(Math.Sign(xSingle1)));
Console.WriteLine(str, "Double ", xDouble1, Test(Math.Sign(xDouble1)));
Console.WriteLine(str, "Decimal", xDecimal1, Test(Math.Sign(xDecimal1)));
Console.WriteLine($"{nl}The following type is not CLS-compliant.");
Console.WriteLine(str, "SByte ", xSbyte1, Test(Math.Sign(xSbyte1)));
}
public static string Test(int compare)
{
if (compare == 0)
return "equal to";
else if (compare < 0)
return "less than";
else
return "greater than";
}
}輸出：
Test the sign of the following types of values: Byte : 0 is equal to zero. Int16 : -2 is less than zero. Int32 : -3 is less than zero. Int64 : -4 is less than zero. Single : 0 is equal to zero. Double : 6 is greater than zero. Decimal: -7 is less than zero. The following type is not CLS-compliant. SByte : -101 is less than zero.
示例2: Main
//引入命名空間
using System;

public static void Main() {
Console.WriteLine("Math.Sign(1) = {0}", Math.Sign(1));
Console.WriteLine("Math.Sign(-1) = {0}", Math.Sign(-1));
Console.WriteLine("Math.Sign(0) = {0}", Math.Sign(0));
}
