How do create a DataTable in C#?

I did like this:

 DataTable dt = new DataTable();
 dt.clear();

The easiest way is to create a DtaTable as of now

DataTable table = new DataTable
{
    Columns = {
        "Name", // typeof(string) is implied
        {"Marks", typeof(int)}
    },
    TableName = "MarksTable" //optional
};
table.Rows.Add("ravi", 500);
