Replace()
功能(英): Returns a string in which a specified sub-string has been replaced with another substring a specified number of times.
功能(中):替换变量或者字符串(strToBeSearched)中特定的字符(strSearchFor)为指定的字符(strReplaceWith )，甚至可以设置从第几个(start )出现的开始替换，共替换多少个(count )。
语法: Replace(strToBeSearched, strSearchFor, strReplaceWith , start , count , compare)
条件(英): strToBeSearched is a string expression containing a sub-string to be replaced; strSearchFor is the string expression to search for within strToBeSearched; strReplaceWith is the string expression to replace sub-string strSearchFor; start (optional) is the numeric character position to begin search; count (optional) is a value indicating the comparision constant.(看不懂的看例子即可理解)
例子: <%
　　strTest = "This is an apple!"
　　response.write Replace(strTest, "apple", "orange")
　　%>
运行结果: This is an orange!

IPSC附言：在BBSXP中用到的和例子中的一样，我的插件中也很常用此语法，至于更高级的功能，设置从第几个出现的开始替换，共替换多少个这样的功能，BBSXP中很少用。

比较了一下,ASP中 设置从第几个出现的开始替换,但在.NET中,这个 start 却不是指第几个出现,而是指 指定字符串的第几个字符!

如:

<%
Dim test="01-My love is Nongnong-02-My love is Nongnong-03-My love is Nongnong-04-My love is Nongnong-05-My love is Nongnong-06-My love is Nongnong"
response.write(Replace(test,"Nongnong","Pet",6,3))
%>

运行结果:

love is Pet-02-My love is Pet-03-My love is Pet-04-My love is Nongnong-05-My love is Nongnong-06-My love is Nongnong
