Entity of CRM rapid development

When we operate entity in the background code, it is basically written as follows:

/* Creator: the blog of caidao jushi
* Creation date: January 1, July 5, 2014
*/

Namespace net. CRM. Entity
{
Using system;
Using Microsoft. xrm. SDK;

/// <Summary>
/// Basic mode --- entity
/// </Summary>
Public class entitydemo
{
Public void run (entity)
{
If (isnotnull (entity, "new_int "))
{
// Obtain the value of an int Field
Int new_int = entity. getattributevalue <int> ("new_int ");
}
If (isnotnull (entity, "new_string "))
{
// Obtain the value of a string field
String new_string = entity. getattributevalue <string> ("new_string ");
}
If (isnotnull (entity, "new_float "))
{
// Obtain the value of a float Field
Float new_float = entity. getattributevalue <float> ("new_float ");
}
If (isnotnull (entity, "new_money "))
{
// Obtain the value of the money Field
Decimal new_money = entity. getattributevalue <money> ("new_money"). value;
}
If (isnotnull (entity, "new_picklist "))
{
// Obtain the value of a field of the optionsetvalue type (drop-down box ).
Int new_picklist = entity. getattributevalue <optionsetvalue> ("new_picklist"). value;
}
If (isnotnull (entity, "new_lookup "))
{
// Obtain the value of an entityreference field.
Entityreference new_lookup = entity. getattributevalue <entityreference> ("new_lookup ");
}
}

/// <Summary>
/// Determine whether a field of the object is null
/// </Summary>
/// <Param name = "entity"> entity </param>
/// <Param name = "name"> Field name </param>
Public bool isnotnull (entity, string name)
{
Return entity. Contains (name) & entity. attributes [name]! = NULL;
}
}
}

 

It is correct to write in this way, but it is very complicated. The following is a quick writing method:

/* Creator: the blog of caidao jushi
* Creation date: January 1, July 5, 2014
*/

Namespace net. CRM. Entity
{
Using system;
Using Microsoft. xrm. SDK;

/// <Summary>
/// Quick development --- entity
/// </Summary>
Public class entityquickdemo
{
Public void run (entity)
{
If (entity. isnotnull ("new_int "))
{
// Obtain the value of an int Field
Int new_int = entity. toint ("new_int ");
}
If (entity. isnotnull ("new_string "))
{
// Obtain the value of a string field
String new_string = entity. tostring ("new_string ");
}
If (entity. isnotnull ("new_float "))
{
// Obtain the value of a float Field
Float new_float = entity. tofloat ("new_float ");
}
If (entity. isnotnull ("new_money "))
{
// Obtain the value of the money Field
Decimal new_money = entity. tomoney ("new_money ");
}
If (entity. isnotnull ("new_picklist "))
{
// Obtain the value of a field of the optionsetvalue type (drop-down box ).
Int new_picklist = entity. toopint ("new_picklist ");
}
If (entity. isnotnull ("new_lookup "))
{
// Obtain the value of an entityreference field.
Entityreference new_lookup = entity. toer ("new_lookup ");
}
}
}
