示例

下面的示例使用 GetValues 方法来检索中每个标头的值的数组 WebHeaderCollectionThe following example uses the GetValues method to retrieve an array of values for each header in the WebHeaderCollection.

// Create a web request for S"www.msn.com".
HttpWebRequest^ myHttpWebRequest = dynamic_cast<HttpWebRequest^>(WebRequest::Create( "http://www.msn.com" ));
myHttpWebRequest->Timeout = 1000;

// Get the associated response for the above request.
HttpWebResponse^ myHttpWebResponse = dynamic_cast<HttpWebResponse^>(myHttpWebRequest->GetResponse());

// Get the headers associated with the response.
WebHeaderCollection^ myWebHeaderCollection = myHttpWebResponse->Headers;
for ( int i = 0; i < myWebHeaderCollection->Count; i++ )
{
   String^ header = myWebHeaderCollection->GetKey( i );
   array<String^>^values = myWebHeaderCollection->GetValues( header );
   if ( values->Length > 0 )
   {
      Console::WriteLine( "The values of {0} header are : ", header );
      for ( int j = 0; j < values->Length; j++ )
         Console::WriteLine( "\t {0}", values[ j ] );
   }
   else
            Console::WriteLine( "There is no value associated with the header" );
}
myHttpWebResponse->Close();
// Create a web request for "www.msn.com".
 HttpWebRequest myHttpWebRequest = (HttpWebRequest) WebRequest.Create("http://www.msn.com");
myHttpWebRequest.Timeout = 1000;
// Get the associated response for the above request.
 HttpWebResponse myHttpWebResponse = (HttpWebResponse) myHttpWebRequest.GetResponse();

// Get the headers associated with the response.
WebHeaderCollection myWebHeaderCollection = myHttpWebResponse.Headers;

for(int i = 0; i < myWebHeaderCollection.Count; i++) {
    String header = myWebHeaderCollection.GetKey(i);
    String[] values = myWebHeaderCollection.GetValues(header);
    if(values.Length > 0) {
        Console.WriteLine("The values of {0} header are : ", header);
        for(int j = 0; j < values.Length; j++) 
            Console.WriteLine("\t{0}", values[j]);
    }
    else
    {
        Console.WriteLine("There is no value associated with the header");
    }
}
myHttpWebResponse.Close();
    'Create a web request for "www.msn.com".
    Dim myHttpWebRequest As HttpWebRequest = CType(WebRequest.Create("http://www.msn.com"), HttpWebRequest)
myHttpWebRequest.Timeout = 1000
    'Get the associated response for the above request.
    Dim myHttpWebResponse As HttpWebResponse = CType(myHttpWebRequest.GetResponse(), HttpWebResponse)
    
    'Get the headers associated with the response.
    Dim myWebHeaderCollection As WebHeaderCollection = myHttpWebResponse.Headers
    Dim i As Integer
    For i = 0 To myWebHeaderCollection.Count - 1
        Dim header As [String] = myWebHeaderCollection.GetKey(i)
        Dim values As [String]() = myWebHeaderCollection.GetValues(header)
        If values.Length > 0 Then
            Console.WriteLine("The values of {0} header are : ", header)
            Dim j As Integer
            For j = 0 To values.Length - 1
                Console.WriteLine(ControlChars.Tab + "{0}", values(j))
            Next j
        Else
            Console.WriteLine("There is no value associated with the header")
        End If
    Next i 

注解

GetValues 以数组的形式返回指定标头的内容。GetValues returns the contents of the specified header as an array.

适用于

GetValues(Int32)

获取存储在标头集合的 index 位置中的标头值数组。Gets an array of header values stored in the index position of the header collection.

public:
 override cli::array <System::String ^> ^ GetValues(int index);
public override string[]? GetValues (int index);
public override string[] GetValues (int index);
override this.GetValues : int -> string[]
Public Overrides Function GetValues (index As Integer) As String()

参数

index
Int32

要返回的标头索引。The header index to return.

返回

String[]

标头字符串数组。An array of header strings.
