动软.Net代码生成器生成Model插件,适用于Silverlight创建NotifyPropertyChange类
Silverlight创建继承INotifyPropertyChanged接口的类会产生大量如下代码:
代码
///
<summary>
///
说明
///
</summary>
public
string
description
{
get
{
return
_description; }
set
{
if
(_description
!=
value)
{
_description
=
value;
NotifyPropertyChanged(
"
description
"
);
}
}
}
虽然VS的CodeSnippets已经能够简化大量代码输入
但用惯了Codematic从数据库直接生成Model类,感觉CodeSnippets还是效率太低
于是修改了Codematic的BuilderModel组件,使生成Model代码支持Silverlight的需求
感谢李天平大哥对Codematic的开源:)
插件下载地址:http://files.cnblogs.com/zhlei616/BuilderModelSilverlight.rar
下载后将解压包里的LTP.BuilderModel.dll覆盖Codematic安装目录下的同名文件即可
覆盖前请先备份原文件,需要时再替换回来
