c# - Error while sending file to WCF: The request failed with HTTP status 400: Bad Request -

i trying upload file using wcf service. getting the request failed http status 400: bad request at:

ds = wcfspend.registersupplier("blah", new spendwcfref.filedata  {      filename = myfile.filename.tostring(),      bufferdata = file,      fileposition = 1 }); 

wcf:

public dataset registersupplier(string supplierid, filedata file) {     dataset ds = new dataset();     return ds; }  [servicecontract] public interface ispend {      [operationcontract]     dataset executeprocedure(string procedurename, string[] paramsname, string[] paramsvalue, int num);      [operationcontract]     dataset registersupplier(string supplierid, filedata file);      //[operationcontract]     //bool uploadfiledata(filedata filedata); }  [datacontract] public class filedata {     [datamember]     public string filename { get; set; }      [datamember]     public byte[] bufferdata { get; set; }      [datamember]     public int fileposition { get; set; } } 

application:

ds = wcfspend.registersupplier("blah", new spendwcfref.filedata {      filename = myfile.filename.tostring(),      bufferdata = file, fileposition = 1 }); 

apllication config file:

there few things resulting in error seeing. first thing recommend assign binding configurations created explicitly defined endpoint. this:

<!-- goes in <system.servicemodel> section --> <services>   <service name="myservice">     <endpoint address=""                binding="wshttpbinding"               bindingconfiguration="mybindingforbigarrays"               contract="<namespace>.ispend" />   </service> </services> 

the above configuration service. make sure qualify contract name namespace, , service name needs same name in markup of .svc file.

you similar client, except <client> tag, rather <service>.

if don't specify binding configuration use in endpoint, wcf use default (lower) values binding type selected. alternative make binding configuration default kind of binding, omitting name attribute.

if doesn't solve issue, can try adjusting maxrequestlength value <httpruntime> element in <system.web>. <system.web> child of <configuration>:

<system.web>     <httpruntime maxrequestlength="2147483647" /> </system.web>
