1.修改WebService接收长度
<binding name="IAuthServiceSoap11Binding" maxBufferSize="2147483647"
????????????????????maxReceivedMessageSize="2147483647"/>
???????<binding name="ICuServiceSoap11Binding" maxBufferSize="2147483647"
????????????????????maxReceivedMessageSize="2147483647"/>
或者
<binding name="IAuthServiceSoap12Binding">
?????????<textMessageEncoding messageVersion="Soap12" />
?????????<httpTransport ?maxBufferSize="2147483647"
????????????????????maxReceivedMessageSize="2147483647"/>
???????</binding>
???????<binding name="ICuServiceSoap12Binding">
?????????<textMessageEncoding messageVersion="Soap12" />
?????????<httpTransport maxBufferSize="2147483647"
????????????????????maxReceivedMessageSize="2147483647"/>
???????</binding>
2. 设置WebService认证的用户名和密码
<basicHttpBinding>
???????<binding name="IWsOpsServiceSoap11Binding" maxBufferSize="2147483647"
????????????maxReceivedMessageSize="2147483647" >
?????????<security mode="TransportCredentialOnly">
???????????<transport clientCredentialType="Basic"/>
???????????<message clientCredentialType="UserName"/>
?????????</security>
???????</binding>
?????</basicHttpBinding>
string address = string.Format("http://{0}:{1}/ops/services/IWsOpsService.IWsOpsServiceHttpSoap11Endpoint/", ip, port);
var client = new WsOpsService.WsOpsServicePortTypeClient("IWsOpsServiceHttpSoap11Endpoint", address);
???????????client.ClientCredentials.UserName.UserName = "admin";
???????????client.ClientCredentials.UserName.Password = "123456";
