快速开发平台CreateObject函数的用法

在平台开发中,常常会使用到加载一些外部的dll或者调用一些方法,那么,一般情况下,均可通过LoadAssembly来加载。
dim obj= LoadAssembly(程序集名称,要加载的类名)

如下面语句:

 dim regex= LoadAssembly("System.dll","System.Text.RegularExpressions.Regex","^[0-9]*$")
    '参数是需要验证的字符串,返回结果为该字符串是否符合规则
    dim temp=regex.IsMatch("123"))

但是如果是系统本身已加载的dll,则没有必要再用LoadAssembly来加载,其一是因为LoadAssenbly必须加载本目录下的文件,其二是因为从文件加载时速度会比较慢。
实际上,System.dll在系统中已经加载,所以我们只需要用CreateObject来创建即可,用法如下:

dim regex=createObject("System.Text.RegularExpressions.Regex","^[0-9]*$")
dim temp=regex.IsMatch("123")
msgbox(temp)
直接用CreateObject来创建已经加载了的dll文件中的类。
今天整理了平台启动后所加载的所有dll文件,供大家参考,以下DLL中的类,均可用CreateObject进行创建:

mscorlib.dll
DLSOFT.dll
System.Windows.Forms.dll
System.dll
System.Drawing.dll
FWFramework.Client.MainPlat.dll
DevExpress.Utils.v11.1.dll
System.Data.dll
System.Xml.dll
FWFramework.Client.Common.dll
FWFramework.Common.dll
mscorlib.resources.dll
FWFramework.TableReader.dll
