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, setPublic Property Encoding As Encoding属性值
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。
