Hi, I have created a WCF services which is used by Win32 application. I have added a service to upload and download the large file via WCF services, to transfer a file I am using byte[] array. because my files are stored in the database. I am passing an object of class which have following data fields.

C#

public long FileID;
public string FileName;
public string FileMIME;
public byte[] FileStream;

and few more field which are type of String but they are not related with Uploading file.
The problem with the service is that i'm not able to upload file size more than 16kb, however i am able to download a file of 100kb+. I have googled a lot about this problem and modified my web.config and app.config file as follow.

web.config file

You increase the timeout period in web.config

XML

<system.web>
  <httpRuntime executionTimeout="240" maxRequestLength="20480" />
</system.web>

Solution 3

@sixthplanets: thank you for help. I have gone through all this article and after that i have modified my web.config and app.config a bit.
i.e.: i have changed my

HTML

transferMode="Buffered" to transferMode="Streamed"

and this throws an error for bad request 400

here i am sharing my WCF function with you

C#

public CAIS_FileAttachmentInfoBO downloadfile(long FileID) 
var objAttachment_DAL = objEntity_DAL.FileAttachment1
                                     .Where(us => us.FileID== FileID)
                                     .Select(us => new
                                     {
                                     us.FileID,
                                     us.FileMIME,
                                     us.FileName,                                                                                                                                        
                                     us.FileStream
                                     })
                                     .FirstOrDefault(); 
 CAIS_FileAttachmentInfoBO objFileAttachmentBO =
                                     new CAIS_FileAttachmentInfoBO();
                    if (objAttachment_DAL != null && objAttachment_DAL.FileID > 0)
                    {
                        objFileAttachmentBO.FileName = objAttachment_DAL.FileName;
                        objFileAttachmentBO.FileStream = objAttachment_DAL.FileStream;
                        objFileAttachmentBO.Is_Password = false;
                        objFileAttachmentBO.Password = "";
                        objFileAttachmentBO.FileID = objAttachment_DAL.FileID;
                    }
                        return objFileAttachmentBO;

here "CAIS_FileAttachmentInfoBO" is my class which has the 5 data field as used in function.
I don't think that the problem with my function

thank you. :)
