Add String Variable to MySQL Statement in C#

Question

Hi everyone,

I'm a C# newbie. I've done a thorough search on Google, but I still can't seem to find a fitting solution to this very simple problem.

I'm simply trying to insert a string variable into an SQL INSERT statement. Problem is, I can't seem to get the syntax right (even after viewing this solution: http://www.c-sharpcorner.com/Forums/ShowMessages.aspx?ThreadID=41667).

Here's the code:

string dataSetName = textBox1.Text;

string insertQuery = "INSERT INTO ntxy1 values (" + n + "," + t + "," + x + "," + y + "," + "'dataSetName'" + ");";

What gets added as of now is the value "dataSetName" and not the actual value of the variable dataSetName (which is whatever is inputted in textBox1).
 
I know that the problem has to do with dataSetName being a string variable because all the other variables (n, t, x, and y), which are ints, work fine.

Hope my question is clear enough.

I'm pretty sure I'm just getting something wrong with the syntax. Any help?

Thanks in advance!
