WebService SOAP编码UTF-16而不是UTF-8

是否可以强制c# .NET中的WebService使用编码UTF-16而不是UTF-8?

我已经创建了一个简单的WebService来接收XML文档。

WebService.asmx 

public class WebApplication1 : WebService
{
    [WebMethod(Description = "Test")]
    public string Test(XmlDocument xmlDocument)
    {
        return "Test";
    }
}


POST /WebService.asmx HTTP/1.1
Host: localhost
Content-Type: text/xml; charset=utf-8
Content-Length: length
SOAPAction: "http://tempuri.org/Test"
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <Test xmlns="http://tempuri.org/">
      <xmlDocument>xml</xmlDocument>
    </Test>
  </soap:Body>
</soap:Envelope>

如果我尝试传递一个UTF-16编码的XML文档，我会得到以下错误:

XML Content:
<?xml version="1.0" encoding="utf-16"?> <Affiliate xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" leadinnumber="ABCDABCD" xmlns:xsd="http://www.w3.org/2001/XMLSchema" mediaid="30000">

    <Tel>02034056978</Tel>
    <Email>adfsdfsdfsd@live.co.uk</Email>
  </Details>
</Affiliate>

任何帮助将不胜感激:-)

WebService SOAP编码UTF-16而不是UTF-8

你必须配置你的web服务。去Web的全球化部分。配置UTF-16而不是UTF-8。全球化标签的requestEncoding和responseEncoding属性应该设置为UTF-16。

<globalization requestEncoding="utf-8" responseEncoding="utf-8"/>

必须转换为

<globalization requestEncoding="utf-16" responseEncoding="utf-16"/>

此更改将允许web服务接受请求并以UTF-16发送响应。

编辑

通过代码手动设置编码，可以使用以下代码:

        // Set the path of the config file.
        string configPath = "";            
        Configuration config = WebConfigurationManager.OpenWebConfiguration(configPath);
        GlobalizationSection configSection = (GlobalizationSection)config.GetSection("system.web/globalization");            
        configSection.RequestEncoding = Encoding.Unicode;
        configSection.ResponseEncoding = Encoding.Unicode;
