How to parse string to integer in c#?

How to parse string to integer in c#?, someone asked me to explain?

In this article, I will show to convert from string to int by parsing.  Here I want to increment id field in xml for new entries. In XML, data fields are in a string so that I needed to convert it to int.


  DataSet ds = XmlGridView.DataSource as DataSet;
  DataRow dr = (DataRow)ds.Tables[0].Rows[ds.Tables[0].Rows.Count - 1];
  XmlElement ID = MyXmlDocument.CreateElement("ID");
  int x = Int32.Parse(dr["ID"].ToString()); // parse string to integer c#
  x++;       // incrementing value
  ID.InnerText = x.ToString();//assigning incremented valuee to the xml field


c# convert string into int
