String.EndsWith 方法 (String, Boolean, CultureInfo)

 

确定在使用指定的区域性进行比较时此字符串实例的结尾是否与指定的字符串匹配。

命名空间:   System
程序集:  mscorlib(位于 mscorlib.dll)

public bool EndsWith(
	string value,
	bool ignoreCase,
	CultureInfo culture
)

参数

value
Type: System.String

要与此实例末尾的子字符串进行比较的字符串。

ignoreCase
Type: System.Boolean

若要在比较过程中忽略大小写,则为 true;否则为 false

culture
Type: System.Globalization.CultureInfo

确定如何对此实例与 value 进行比较的区域性信息。 如果 culturenull,则使用当前区域性。

返回值

Type: System.Boolean

如果 true 参数与此字符串的末尾匹配,则为 value;否则为 false

Exception Condition
ArgumentNullException

valuenull

This method compares the value parameter to the substring at the end of this string that is the same length as value, and returns a value that indicates whether they are equal. To be equal, value must be a reference to this same instance or match the end of this string.

This method performs a word (culture-sensitive) comparison using the specified casing and culture.

The following example determines whether a string occurs at the end of another string. The M:System.String.EndsWith(System.String,System.Boolean,System.Globalization.CultureInfo) method is called several times using case sensitivity, case insensitivity, and different cultures that influence the results of the search.

// This code example demonstrates the 
// System.String.EndsWith(String, ..., CultureInfo) method.

using System.Threading;
using System.Globalization;

class Sample 
{
    public static void Main() 
    {
    string msg1 = "Search for the target string \"{0}\" in the string \"{1}\".\n";
    string msg2 = "Using the {0} - \"{1}\" culture:";
    string msg3 = "  The string to search ends with the target string: {0}";
    bool result = false;
    CultureInfo ci;

// Define a target string to search for.
// U+00c5 = LATIN CAPITAL LETTER A WITH RING ABOVE
    string capitalARing = "\u00c5";

// Define a string to search. 
// The result of combining the characters LATIN SMALL LETTER A and COMBINING 
// RING ABOVE (U+0061, U+030a) is linguistically equivalent to the character 
// LATIN SMALL LETTER A WITH RING ABOVE (U+00e5).
    string xyzARing = "xyz" + "\u0061\u030a";

// Clear the screen and display an introduction.
    Console.Clear();

// Display the string to search for and the string to search.
    Console.WriteLine(msg1, capitalARing, xyzARing);

// Search using English-United States culture.
    ci = new CultureInfo("en-US");
    Console.WriteLine(msg2, ci.DisplayName, ci.Name);

    Console.WriteLine("Case sensitive:");
    result = xyzARing.EndsWith(capitalARing, false, ci);
    Console.WriteLine(msg3, result);

    Console.WriteLine("Case insensitive:");
    result = xyzARing.EndsWith(capitalARing, true, ci);
    Console.WriteLine(msg3, result);
    Console.WriteLine();

// Search using Swedish-Sweden culture.
    ci = new CultureInfo("sv-SE");
    Console.WriteLine(msg2, ci.DisplayName, ci.Name);

    Console.WriteLine("Case sensitive:");
    result = xyzARing.EndsWith(capitalARing, false, ci);
    Console.WriteLine(msg3, result);

    Console.WriteLine("Case insensitive:");
    result = xyzARing.EndsWith(capitalARing, true, ci);
    Console.WriteLine(msg3, result);
    }
}

/*
Note: This code example was executed on a console whose user interface 
culture is "en-US" (English-United States).

This code example produces the following results:

Search for the target string "Å" in the string "xyza°".

Using the English (United States) - "en-US" culture:
Case sensitive:
  The string to search ends with the target string: False
Case insensitive:
  The string to search ends with the target string: True

Using the Swedish (Sweden) - "sv-SE" culture:
Case sensitive:
  The string to search ends with the target string: False
Case insensitive:
  The string to search ends with the target string: False
