System.Net.WebException exception

I am getting the following excepti开发者_JAVA技巧on in my ASP.net project

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Net.WebException: The request failed with HTTP status 404: Not Found.

Source Error: Line 76: [System.Web.Services.Protocols.SoapDocumentMethodAttribute("tempuri.org/GetUserByName";, RequestNamespace="tempuri.org/";, ResponseNamespace="tempuri.org/";, Use=System.Web.Services.Description.SoapBindingUse.Literal, ParameterStyle=System.Web.Services.Protocols.SoapParameterStyle.Wrapped)] Line 77: public DTO_User GetUserByName(string name) { Line 78: object[] results = this.Invoke("GetUserByName", new object[] { Line 79: name}); Line 80: return ((DTO_User)(results[0]));

I think that there must be some problem with my connection string but I don't have concrete idea about that.

I am using VS 2010 with sql server management studio where my Database is residing....

Please help me in this regard.

In general a 404 status means a resource is not found. in this case, most likely it means the page you are trying to access does not exist.
