C# - How to sort a DataTable?

One way to sort a DataTable is to set "Sort" property of DefaultView of a DataTable and then convert the sorted DataView to DataTable by .ToTable() method.

DataView.Sort Property

DataView.ToTable Method

Example:

DataTable myDT = new DataTable();
Random rndm = new Random();

myDT.Columns.Add("iValue", typeof(System.Int32) );
for (int i = 0; i < 10; i++)
{
   DataRow myDR = myDT.NewRow();
   myDR["iValue"] = rndm.Next();
   myDT.Rows.Add(myDR);
}

string sortExp = "iValue";
string sortOrder = "DESC";
myDT.DefaultView.Sort = sortExp + " " + sortOrder;
myDT = myDT.DefaultView.ToTable();
