Hi,

I'm trying to convert an excel file to byte array and passing the same to WCF service method.
I'm getting the following exception. Please help me to resolve this issue.

This is the below code chunk where I'm getting error and
SaveData(***) method is the one which calls the WCF service

C#

string strFile = ViewState[GlobalConstants.strVsfilePath].ToString();
                    DataTable dtSaveData = new DataTable();
                    dtSaveData = (DataTable)ViewState[GlobalConstants.strVsOrginal];
                    DataSet dsSaveData = new DataSet();
                    dsSaveData.DataSetName = "dsfff";
                    dsSaveData.Tables.Add(dtSaveData);
                    dsSaveData.Tables[0].TableName = "dtfff";
                    string strResult = string.Empty;
                    MemoryStream stream = new MemoryStream();
                    dtSaveData.WriteXml(stream, true);
                    stream.Seek(0, SeekOrigin.Begin);
                    StreamReader sr = new StreamReader(stream);
                    string strInputXML = sr.ReadToEnd();
                    string strModifiedXml = strInputXML.Replace("+05:30", "");
                    byte[] btData = FileToByteArray(strFile);
                    File.Delete(strFile);
                    //cByteTransfer objByteTransfer = new cByteTransfer();
                    //objByteTransfer.BTransfer = btData;
                    Stream streamData = new MemoryStream(btData);

                    adminsvc.SaveData(strModifiedXml, dsSaveData.DataSetName, dsSaveData.Tables[0].TableName, strType, strLoginName, "FIXED", btData, (string)ViewState["strWorkbookName"], (string)ViewState["SheetName"]);

Will you think by yourself: what's the use to show some exception stack trace without showing the code sample and pointing out where the exception was thrown?

Could you include the code you are using to stream the file also.

I have set the maxStringContentLength="65536000" in basichttpbinding-->binding tag and it worked.

And also added the name of the binding used under basichttpbinding-->binding here into the endpoint tag as an attribute binding="basicBinding"

Please find the configuration used as below

HTML

<system.serviceModel>
    <bindings>

      <basicHttpBinding>
       
        <binding name="basicBinding" closeTimeout="00:10:00" openTimeout="00:10:00" sendTimeout="00:10:00" maxBufferSize="2147483647"  maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647">
          <readerQuotas maxDepth="2147483647" maxStringContentLength="65536000"
          maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647"/>
        </binding>
        </basicHttpBinding>
    </bindings>
    <behaviors>
      <serviceBehaviors>
        <behavior name="MyServiceTypeBehaviors">
          <dataContractSerializer maxItemsInObjectGraph="2147483647"/>
          <serviceMetadata httpGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="true" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <services>
      <service name="MY_SERVICE.cMY_Module"
             behaviorConfiguration="MyServiceTypeBehaviors">
        <endpoint address="http://localhost:1111/MY_Service.svc" binding="basicBinding"
             contract="MY_SERVICE.IMyService" bindingConfiguration="basicHttpBinding"/>
        <endpoint contract="IMetadataExchange"
           binding="mexHttpBinding" address="mex"/>
      </service>
    </services>
  </system.serviceModel>

Thanks & Regards,
