A: add operation

Method Prototype:
public BOOL  the Insert () public BOOL  the Insert ( BOOL  AutoSetValue)  
 

 

Example 1:

Action MAction  = new new  MAction (TableNames.Users); action.Set (Users.UserName,  " passing the fall " ); // or from control values action.GetFrom (txtUserName); action.Insert (); action.Close () ;  

 

Example 2:

Action MAction  = new new  MAction (TableNames.Users); action.SetAutoPrefix ( " TXT " ); // set control prefix may be provided a plurality of action.Insert ( to true ); action.Close ();  

 

Another: SetAutoPrefix automatic setting method prefix

方法原形： public   void  SetAutoPrefix( string  autoPrefix,  params   string [] otherPrefix)

 

A plurality of prefixes may be provided as an example:

action.SetAutoPrefix( " txt " , " ddl " , " lab " );

 

 

 

Two: delete

Method Prototype:
public BOOL  the Delete () public BOOL  the Delete ( Object WHERE )  
   

 

Example 1:

MAction action  =   new  MAction(TableNames.Users);
action.Set(Users.ID,  1 );
action.Delete();
action.Close();

 

Example 2:

MAction action  =   new  MAction(TableNames.Users);
action.Delete( " id=1 or UserName='路过秋天' " );
action.Close();

Example 3:

MAction action  =   new  MAction(TableNames.Users);
if  (action.Fill( 1 ))
{
     // 处理其它事情
    if  (action.Delete())
   {
       action.Close();
   }
}

 

 

III: update

public   bool  Update()
public   bool  Update( object   where )
public   bool  Update( object   where ,  bool  AutoSetValue)

Example 1:

MAction action  =   new  MAction(TableNames.Users);
action.Set(Users.ID,  1 );
action.Set(Users.Password,  " http://cyq1162.cnblogs.com " );
action.Update(); // 更新UserID为1的密码
action.Close();

 

Example 2:

MAction action  =   new  MAction(TableNames.Users);
action.Set(Users.Password,  " http://cyq1162.cnblogs.com " );
action.Update( " UserName='路过秋天' " );
action.Close();

 

Example 3:

Action MAction  = new new  MAction (TableNames.Users); action.SetAutoPrefix ( " TXT " ); action.Set (Users.Password,  " http://cyq1162.cnblogs.com " ); action.GetFrom (txtUserName); Action. the Update ( " ID =. 1 " , to true ); action.Close (); // description, in addition to explicitly set the password and user name taken from a control, did not show the other values of other attributes of the users table, from txt the value for the prefix control. // other properties similar to automatically obtain the value of: taking Request value [ "txtFullName"] assigns FullName property.

This section explains by, you should be able to grasp the basic CRUD operations for data.
If you have an unknown in use, to please leave a message.
