How to call MySQL stored procedure with multiple input values from ASP.NET

问题

This is my MySQL stored procedure.

    create procedure InsertIntotblStudentProc (PStudentId VARCHAR(10), PStudentName VARCHAR(10))
    begin
    insert into tblStudent (StudentId, StudentName) values (PStudentId, PStudentName);
end;

Here's my ASP code.

   `MySqlCommand cmd = new MySqlCommand("InsertIntotblStudent", con);
    cmd.CommandType = CommandType.StoredProcedure;
    cmd.Parameters.AddWithValue("PStudentId", TextBox1.Text);`

I stopped here as I want to call procedure with two parameters and my other parameter is in TextBox2.

Help me with suggestions.

You can add mutiple parameters in command.Parameters, refer the below code for the same.

        var connectionString = ""; // Provide connecction string here.
    using (var connection = new MySqlConnection(connectionString))
    {
        MySqlCommand command = new MySqlCommand("InsertIntotblStudent", connection);
        command.CommandType = CommandType.StoredProcedure;
        command.Parameters.Add(new MySqlParameter("PStudentId", TextBox1.Text));
        command.Parameters.Add(new MySqlParameter("PStudentName", TextBox2.Text));
        command.Connection.Open();
        var result = command.ExecuteNonQuery();
        command.Connection.Close();
    }

回答2:

consider using list of MySqlParameter like this:

    var sqlParameters = new List<MySqlParameter>();
    sqlParameters.Add(new MySqlParameter { MySqlDbType = MySqlDbType.Int32, ParameterName = "@valuename", Value = textbox1 });
        .
        .
    cmd.Parameters.AddRange(sqlParameters.ToArray());
