This is my controller function,

[HttpPost]
public HttpResponseMessage Validate(Login login)
{
try
{
Login = new LoginCRUD();

return new HttpResponseMessage()
{
Content = new StringContent(string.Concat(Login.Validate(login)), Encoding.UTF8, "application/json")
};
}
catch (Exception ex)
{
throw ex;
}
}

This is my Class function,

public object Validate(Login login)
{
try
{
DataSet ds = new DataSet();

object[] objParamValue = { login.Password, login.User_Name };

ds = sqlhelper.GetDataset(ConnectionString, "usp_getlogindetails", ProcedureParameters.GetLoginDetailsParameters, objParamValue);
//ds = sqlhelper.GetDataset(ConnectionString, "usp_getlogindetails1", null, null);

return JsonUtility.serializetoJSON(ds.Tables[0]);
}
catch(Exception ex)
{
throw ex;
}
}

Also terms like "not working" are meaningless and don't give any information people can use to try and help you.

For anybody to provide you with any help on this (or other issues), you will need to provide better information than you have provided here. A lot of the information provided is not relevant as I understand it you are receiving nulls at the service boundary so the downstream code is not part of the problem - the problem could be how you are invoking the api - have you tested this using a Rest test client (I use a Firefox plugin and/or fiddler)

What does your message look like (I am guessing you are doing a Post) what is the Method, URL, Content-Type and Body...

e.g.

Method : POST URL: http://loalhost:34715/odata/Products
Headers : Content-Type: Application/Json
Body :
{
"ID": 6,
"Description": "Tomato",
"SalePrice": "15",
"ProductGroup": "Vegetable"
}

Providing something like this may help others to help you - I suspect there is an issue with the body of your message that is causing the problem.

One comment on your code - the try catch block is not do anything - if you remove it the code will behave the same as seen from the consumer. Don't catch exceptions unless you are going to do something with them Equally you should not be capturing general exceptions.
