为什么c# Web客户端显示?法语字符

Question

我的web服务客户端返回法语字符的?。我的客户正在调用Apache上的axis2/c web服务。我使用wsdl.exe来生成一个c#代理类。当我在TCPMON中查看返回时，我可以正确地看到法语字符，但在c#中，它们只是显示为?以下是我从TCPMON会话捕获的请求和响应:

任何帮助都将非常感激。下面是我在wsdl.exe生成的代理类中的函数:

    [System.Web.Services.Protocols.SoapDocumentMethodAttribute("", RequestNamespace="http://Common.media.jda.com/service", ResponseNamespace="http://Common.media.jda.com/service", Use=System.Web.Services.Description.SoapBindingUse.Default, ParameterStyle=System.Web.Services.Protocols.SoapParameterStyle.Wrapped)]
    [return: System.Xml.Serialization.XmlElementAttribute("getCriteriaReturn")]
    public CriteriaRec[] getCriteria(int userId) {
        object[] results = this.Invoke("getCriteria", new object[] {
                    userId});
        return ((CriteriaRec[])(results[0]));
    }

Answer 1

我可以通过创建和覆盖函数来解决这个问题:

protected override WebResponse GetWebResponse(WebRequest request)
{
    WebResponse webResponse = base.GetWebResponse(request);
    webResponse.Headers["Content-Type"] = "text/xml; charset=iso-8859-15";
    return webResponse;
}

这很好。另外，我指定了requestEncoding来处理发回的数据:

myservice.RequestEncoding = System.Text.Encoding.GetEncoding("iso-8859-15");
