UriTemplateMatch.QueryParameters 属性

定义

命名空间:

System

程序集:

System.ServiceModel.dll

获取查询字符串参数及其值的集合。

public:
 property System::Collections::Specialized::NameValueCollection ^ QueryParameters { System::Collections::Specialized::NameValueCollection ^ get(); };

public System.Collections.Specialized.NameValueCollection QueryParameters { get; }

member this.QueryParameters : System.Collections.Specialized.NameValueCollection

Public ReadOnly Property QueryParameters As NameValueCollection

属性值

NameValueCollection

一个包含查询字符串参数及其值的 NameValueCollection 实例。

示例

下面的代码演示如何访问 QueryParameters 属性。

UriTemplate template = new UriTemplate("weather/{state}/{city}?forecast=today");
Uri baseAddress = new Uri("http://localhost");
Uri fullUri = new Uri("http://localhost/weather/WA/Seattle?forecast=today");

Console.WriteLine("Matching {0} to {1}", template.ToString(), fullUri.ToString());

// Match a URI to a template
UriTemplateMatch results = template.Match(baseAddress, fullUri);
if (results != null)
{
    Console.WriteLine("QueryParameters:");
    foreach (string queryName in results.QueryParameters.Keys)
    {
        Console.WriteLine("    {0} : {1}", queryName, results.QueryParameters[queryName]);
    }
    Console.WriteLine();
}
// Code output:
//  QueryParameters:
//  forecast : today

Dim template As New UriTemplate("weather/ state}/ city}?forecast=today")
Dim baseAddress As New Uri("http://localhost")
Dim fullUri As New Uri("http://localhost/weather/WA/Seattle?forecast=today")

Console.WriteLine("Matching  0} to  1}", template.ToString(), fullUri.ToString())

'Match a URI to a template
Dim results As UriTemplateMatch = template.Match(baseAddress, fullUri)
If (results IsNot Nothing) Then

    Console.WriteLine("QueryParameters:")
    For Each queryName As String In results.QueryParameters.Keys
        Console.WriteLine("     0} :  1}", queryName, results.QueryParameters(queryName))
    Next
    Console.WriteLine()
End If
'Code output:
' QueryParameters:
' forecast : today

注解

原始 URI 中的所有查询字符串名称/值对都会出现在此集合中，即使没有在匹配的模板字符串中显式指定它们也是如此。 此集合中的值已将所有转义序列转换为实际字符。
