Connection string error used in ASP.Net project...

Question

I have face the problem of connection string which gives me the error as:

Format of the initialization string does not conform to specification starting at index 0.

Pls give me suggestions on this problem. 

 

the code which i had written is:

Web.Config:

<connectionStrings>

<add name="conn" connectionString="initial catalog=NtierDemo;integrated security=true;server=yash-pc" providerName="System.Data.SqlClient"/>

</connectionStrings>

and

public static string GetconString()

{

return ConfigurationManager.ConnectionStrings["conn"].ConnectionString;

}
