First, create a base class cname, as shown below:
TypeCname = ClassPrivate{Public declarations}Public{Protected Declarations}Function getfirstname: string;

Way One: Use the BindingSource AddNew
New record, recommended for use, cursor position in current new record, and processing edit state
DataRow Thisrow = ((DataRowView) usersbindingsource.addnew ()). Row;
thisrow["OID"] = 5;
thisrow["CNAME"] = "New user";
thisrow["sex"] = "M";
Mode two: Using the NewRow of the DataTa

using common array syntax.Using this method, you can access the value of a particular column either by specifying the name of the data column or by specifying the number of the data column.The first column is numbered 0, the second column number is 1, and so on. For example:Object value1=mydatareader["learning number"];Object Value1=mydatareader[0];Item PropertiesEach of the DataReader classes defines an item property that returns an object for a Code field property.The Item property is the ind
