everything is fine model state is also getting treue but when it is checking the connection string at that time why the connection string is showing closed.

int rowAffected = 0;

using (IDbConnection con = new SqlConnection(ConnectionString))

{

if (con.State == ConnectionState.Closed)

con.Open();

DynamicParameters parameters = new DynamicParameters();

parameters.Add("@Name", obj.Name, DbType.String);

parameters.Add("@Gender", obj.Gender, DbType.String);

parameters.Add("@Address", obj.Address, DbType.String);

parameters.Add("@Mobile", obj.Mobile, DbType.String);

rowAffected = con.Execute("InsertUserDetails", parameters, commandType: CommandType.StoredProcedure);

}

return rowAffected;
