Question

How do create a DataTable in C#?

I did like this:

 DataTable dt = new DataTable();
 dt.clear();
 dt.Columns.Add(\"Name\");
 dt.Columns.Add(\"Marks\")

You can also pass in an object array as well, like so:

DataTable dt = new DataTable();
dt.Clear();
dt.Columns.Add("Name");
dt.Columns.Add("Marks");
object[] o = { "Ravi", 500 };
dt.Rows.Add(o);

Or even:

dt.Rows.Add(new object[] { "Ravi", 500 });
