C# 找出一个子串在另一字符串中出现的所有位置
如果需要在一个字符串中找出一个特定串所有出现的位置，可以采用下面代码：<div style="padding-right: 5.4pt; padding-left: 5.4pt; background: #e6e6e6; padding-bottom: 4px; width: 95%; padding-top: 4px;">http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gifpublicint[]GetSubStrCountInStr(Stringstr,Stringsubstr,intStartPos)
