c# - 更改c# WebReference url地址

Question

你好， 我有 2 个客户端和 2 个不同的服务器。 生成 wsdl 类后，我在 SoapHttpClientProtocol consructor 中相应地更改客户端的 url 地址。

来自

this.Url = "http://10.0.3.5:88/SomeName/dish

到

this.Url = "http://192.168.20.5:88/SomeOtherName/dish

但我无法在运行时更改 SoapDocumentMethodAttribute。如果不更改它，我的方法不会只返回 null 的 DataSet。更改属性中的所有地址后，一切正常。

[System.Web.Services.Protocols.SoapDocumentMethodAttribute( "http://10.0.3.5:88/SomeName/EuroSoft/ProductTransferExecute", RequestNamespace = "http://10.0.3.5:88/SomeName/dish", ResponseNamespace = "http://10.0.3.5:88/SomeName/dish", Use = System.Web.Services.Description.SoapBindingUse.Literal, ParameterStyle = 

System.Web.Services.Protocols.SoapParameterStyle.Wrapped )]
public System.Data.DataSet ProductTransferExecute( [System.Xml.Serialization.XmlElementAttribute( IsNullable = true )] string department, [System.Xml.Serialization.XmlElementAttribute( IsNullable = true )] string XMLproducts, out int sqlcode ) {}

服务由 Sybase Anywhere 9 数据库生成。是否可以动态更改它？什么需要完全相同才能起作用？

创建一个 CustomSoapHttpClientProtocol:

public class CustomSoapHttpClientProtocol : SoapHttpClientProtocol
{
    public string SoapActionUrl { get; private set; }

    public CustomSoapHttpClientProtocol(string soapActionUrl)
    {
        this.SoapActionUrl = soapActionUrl;
    }
    protected override WebResponse GetWebResponse(WebRequest request)
    {
        const string soapAction = "SOAPAction";
        if (request.Headers.Count > 0 && request.Headers.AllKeys.Contains(soapAction))
        {
            request.Headers[soapAction] = SoapActionUrl;
        }
        WebResponse response = base.GetWebResponse(request);
        return response;
    }

然后在您的代理类中将 SoapHttpClientProtocol 替换为您的 CustomSoapHttpClientProtocol。
