WebClient.Encoding 属性

定义

命名空间:

System.Net

程序集:

System.Net.WebClient.dll

Source:

WebClient.cs

获取或设置用于上传和下载字符串的 Encoding。

public:
 property System::Text::Encoding ^ Encoding { System::Text::Encoding ^ get(); void set(System::Text::Encoding ^ value); };

public System.Text.Encoding Encoding { get; set; }

member this.Encoding : System.Text.Encoding with get, set

Public Property Encoding As Encoding

属性值

Encoding

用于对字符串进行编码的 Encoding。 此属性的默认值是 Default返回的编码。

示例

下面的代码示例演示如何设置此属性的值。

void UploadString( String^ address )
{
   String^ data = "Time = 12:00am temperature = 50";
   WebClient^ client = gcnew WebClient;

   // Optionally specify an encoding for uploading and downloading strings.
   client->Encoding = System::Text::Encoding::UTF8;

   // Upload the data.
   String^ reply = client->UploadString( address, data );

   // Disply the server's response.
   Console::WriteLine( reply );
}

public static void UploadString(string address)
{
    string data = "Time = 12:00am temperature = 50";
    WebClient client = new WebClient();
    // Optionally specify an encoding for uploading and downloading strings.
    client.Encoding = System.Text.Encoding.UTF8;
    // Upload the data.
    string reply = client.UploadString(address, data);
    // Display the server's response.
    Console.WriteLine(reply);
}

Public Shared Sub UploadString(ByVal address As String)

    Dim data As String = "Time = 12:00am temperature = 50"
    Dim client As WebClient = New WebClient()
    '  Optionally specify an encoding for uploading and downloading strings.
    client.Encoding = System.Text.Encoding.UTF8
    '  Upload the data.
    Dim reply As String = client.UploadString(address, data)
    '  Disply the server's response.
    Console.WriteLine(reply)
End Sub

注解

谨慎

WebRequest、HttpWebRequest、ServicePoint和 WebClient 已过时，不应将其用于新开发。 请改用 HttpClient。

UploadString 和 UploadStringAsync 方法在上传字符串之前使用此属性将指定的字符串转换为 Byte 数组。 有关详细信息，请参阅 GetBytes 方法。

使用 DownloadString 或 DownloadStringAsync 方法下载字符串时，WebClient 使用由此返回的 Encoding 将下载的 Byte 数组转换为字符串。 有关详细信息，请参阅 GetString 方法。
