Hey,
I have problem in connecting to sql server database from my android mobile application from C#.net.I am getting following exception for connection string.
System.Data.SqlClient.SqlException: 'System.Net.Security.Native assembly:<unknown assembly> type:<unknown type> member:(null) at (wrapper managed-to-native) Interop+NetSecurityNative.ImportPrincipalName(Interop/NetSecurityNative/
Below is my connection string code
try { fetchquest obj = new fetchquest(); string servdbname = "ExamSim"; string servname = "192.168.0.171"; string serusername = "sa"; string serpasswd = "Success24"; string sqlcon = $"Data Source={servname};Initial Catalog={servdbname};User Id={serusername};Password={serpasswd};Trusted_Connection=true"; SqlConnection sqlconn = new SqlConnection(sqlcon); sqlconn.Open(); SqlDataReader dr; SqlCommand cmd = new SqlCommand("Select * from Questions", sqlconn); dr = cmd.ExecuteReader(); if (dr.HasRows == true) { dr.Read(); obj.Qid = Convert.ToInt32(dr["Qid"]); obj.Qus = dr["Question"].ToString(); } } catch(Exception ex) { Console.WriteLine(ex.Message); throw; }
