Silverlight call WCF common error Silverlight WCF upload Big Data

 

Error 1

Error Description: the remote server returned an error: notfound

Possible cause: the WCF Service limits the number of data packets to a maximum of 65535. Silverlight sends large data packets to the server (the sample slices are directly stored in the database), and WCF returns the preceding error.

During transmission, it is best to use list <string> instead of string as the parameter.

Solution:

(1) modify the servicereferences. clientconfig file on the Silverlight end to increase the buffer size.
< Bindings >  
< Basichttpbinding >  
< Binding Name = "Basichttpbinding_idataservice"  
Maxbuffersize = "2147483647"  
Maxcompute edmessagesize = "2147483647" >  
< Security Mode = "NONE" />  
</ Binding >  
</ Basichttpbinding >  
</ Bindings >

 

System. servicemodel. basichttpbinding binding = new system. servicemodel. basichttpbinding (system. servicemodel. basichttpsecuritymode. None );
Binding. maxcompute edmessagesize = int. maxvalue;
Binding. maxbuffersize = int. maxvalue;
Binding. receivetimeout = timespan. fromminutes (5 );
Binding. sendtimeout = timespan. fromminutes (5 );
Binding. closetimeout = timespan. fromminutes (5 );
Binding. opentimeout = timespan. fromminutes (5 );
Endpointaddress Ep = new endpointaddress ("../dataservice. SVC ");
Mytest. dataservice. dataserviceclient client = new dataserviceclient (binding, EP );

(2) modify the server and add the custom basichttpbinding object to Web. config,
