Question

I’m trying to build out a C# web app that has an input screen. Some of the fields are Qty fields. What could I use as a database type to be able to record a numerical value and how would I write it in my code? Currently using Nchar which records the value but when I try to do some basic adding of Qty1 + Qty2 for example, it doesn’t seem to return a value. This is what I currently have:

nonqueryCommand.Parameters.Add("@Qty1", System.Data.SqlDbType.NChar, 10);

Ive tried numeric and float but they give me something about converting string to int32 errors.

Thanks for the insight.

Answer 1

you can use int type

int qte1 = Convert.ToInt32(yourTextBox1.Text);;
int qte2 = Convert.ToInt32(yourTextBox2.Text);;

int result = qte1 + qte2;
