VersionNotFoundException Class
Represents the exception that is thrown when you try to return a version of a DataRow that has been deleted.
Assembly: System.Data (in System.Data.dll)
The following example creates a DataTable with one DataColumn and ten DataRow objects. After deleting a DataRow, trying to return the removed row's current version causes a VersionNotFoundException exception being thrown.
private void DemonstrateVersionNotFoundException() { // Create a DataTable with one column. DataTable table = new DataTable("NewTable"); DataColumn column = new DataColumn("NewColumn"); table.Columns.Add(column); DataRow newRow; for(int i = 0;i <10;i++) { newRow = table.NewRow(); newRow["NewColumn"] = i; table.Rows.Add(newRow); } table.AcceptChanges(); try { Console.WriteLine("Trying..."); DataRow removedRow = table.Rows[9]; removedRow.Delete(); removedRow.AcceptChanges(); // Try to get the Current row version. Console.WriteLine(removedRow[0,DataRowVersion.Current]); } catch(System.Data.VersionNotFoundException) { Console.WriteLine("Current version of row not found."); } }
