Insert into MySql Table

[Raidzen10]

Im sorry if you have seen this question a thousand times, But ive googled this and still couldnt find a solution. I googled and changed my code a bit but it still doesnt fix my code.

So,i want insert data into my Mysql table from an asp.net page But it kept giving me errors, the lastest of which is "Only MySqlParamaters objects may be stored".

Here is my Code:

MySqlConnection con = new MySqlConnection(ConfigurationManager.ConnectionStrings["MySql"].ConnectionString);

string com = "INSERT INTO Users(Name, Surname, Pass, Email, Type)
VALUES(@Name,@Surname,@Password,@Emailaddr, @type)";

MySqlCommand Com = new MySqlCommand(com, con);

Com.CommandType = CommandType.Text;
Com.Parameters.Add(new MySqlParameter("?Name", MySqlDbType.Text).Value = txtfname.Text);
Com.Parameters.Add(new MySqlParameter("?Surname", MySqlDbType.Text).Value = txtlname.Text);
Com.Parameters.Add(new MySqlParameter("?Password", MySqlDbType.Text).Value = txtpass11.Text);
Com.Parameters.Add(new MySqlParameter("?Emailaddr", MySqlDbType.Text).Value = txtemail.Text);
Com.Parameters.Add(new MySqlParameter("?type", MySqlDbType.Text).Value = "Patient");

con.Open();
Com.ExecuteNonQuery();

con.Close();

string com = "INSERT INTO Users(Name, Surname, Pass, Email, Type)
VALUES(@Name,@Surname,@Password,@Emailaddr, @type)";

MySqlCommand Com = new MySqlCommand(com, con);

Com.CommandType = CommandType.Text;
Com.Parameters.Add(new MySqlParameter("?Name", MySqlDbType.Text).Value = txtfname.Text);

First: I do believe you have a matter due to the use of the "@" parameter that mySql does not like.
In any case, you should be consistent with yourself : you used "?" in the parameters, and you should use it also in the query, like in the following example:

string theQuery = "INSERT INTO Users(Name, Surname, Pass, Email, Type)
VALUES(?Name,?Surname,?Password,?Emailaddr, ?type)";

Second:
you have some special names there:
Name
and expecially
Type
you should surround them in brackets : "[" and "]"

string theQuery = "INSERT INTO Users([Name], Surname, Pass, Email, [Type])
VALUES(?Name,?Surname,?Password,?Emailaddr, ?type)";

Third (less important, this is to make your life better, you can completely disregard the following)
c# is case sensitive, thus you might have a variable named "com" foro the commandString and a variable named "Com" for the Command Object. But let me suggest you to name one of the two in a different way
