Comparer(CultureInfo) 构造函数

定义

命名空间:
System.Collections
程序集:
mscorlib.dll, System.Collections.NonGeneric.dll
程序集:
mscorlib.dll
程序集:
netstandard.dll

使用指定的Comparer值初始化类的新实例CultureInfo。

public:
 Comparer(System::Globalization::CultureInfo ^ culture);
public Comparer(System.Globalization.CultureInfo culture);
new System.Collections.Comparer : System.Globalization.CultureInfo -> System.Collections.Comparer
Public Sub New (culture As CultureInfo)

参数

culture
CultureInfo

CultureInfo要用于新 Comparer。

例外

ArgumentNullException

culture 是 null。

示例

下面的代码示例演示如何根据与 <a0/&a0> 关联的区域性返回不同的值。

using System;
using System.Collections;
using System.Globalization;

public class SamplesComparer  {

   public static void Main()  {

      // Creates the strings to compare.
      String str1 = "llegar";
      String str2 = "lugar";
      Console.WriteLine( "Comparing \"{0}\" and \"{1}\" ...", str1, str2 );

      // Uses the DefaultInvariant Comparer.
      Console.WriteLine( "   Invariant Comparer: {0}", Comparer.DefaultInvariant.Compare( str1, str2 ) );

      // Uses the Comparer based on the culture "es-ES" (Spanish - Spain, international sort).
      Comparer myCompIntl = new Comparer( new CultureInfo( "es-ES", false ) );
      Console.WriteLine( "   International Sort: {0}", myCompIntl.Compare( str1, str2 ) );

      // Uses the Comparer based on the culture identifier 0x040A (Spanish - Spain, traditional sort).
      Comparer myCompTrad = new Comparer( new CultureInfo( 0x040A, false ) );
      Console.WriteLine( "   Traditional Sort  : {0}", myCompTrad.Compare( str1, str2 ) );
   }
}

/*
This code produces the following output.

Comparing "llegar" and "lugar" ...
   Invariant Comparer: -1
   International Sort: -1
   Traditional Sort  : 1

注解

比较过程使用指定的 System.Globalization.CultureInfo 值来确定排序顺序和大小写规则。 字符串比较可能具有不同的结果，具体取决于区域性。 有关区域性特定比较的详细信息，请参阅 System.Globalization 命名空间 和全球化和本地化。
