General conversion between able and object set in C # (using the extension method)

In this case, DataRow is converted to a single entity, and dataTable is converted to a List generic type, which supports time format conversion.

The following methods are all extension methods. The extension method must be written in a static class, and the method should also be static.

• Medium
• (The first parameter type is also called the extension type, that is, the method is used to expand this type)

 

 

1. Convert DataRow to an object

                                      T ToModel<T>( DataRow dr)  T : , ToModel<T>(dr,

2. Convert DataRow to an object and set the time format conversion.

                                                                T ToModel<T>( DataRow dr,  dateTimeToString)  T : ,  (dr !=  ToList<T> 

3. convert a able to an object

                                                      List<T> ToList<T>( DataTable dt,  dateTimeToString)  T : , <T> list =  List<T> (dt != <PropertyInfo> infos =  List<PropertyInfo><PropertyInfo>((T).GetProperties(), p => (dt.Columns.Contains(p.Name) == <T>

4. Conversion implementation code

     SetList<T>(List<T> list, List<PropertyInfo> infos, DataTable dt,  dateTimeToString)  T : ,  (DataRow dr = => (dr[p.Name] != DBNull.Value) tempValue = (dr[p.Name].GetType() == (DateTime) && dateTimeToString == )=);        }
