全部替換功能在VB.net

Question

我怎麼能代替所有的字符串中的字符串varaiable像

dim str = "I am testing and testing and testing" 

更換後「和」

ReplaceAll(str,"and","or") 

如何與案件insentive不區分全部更換sensative？

Answer 1

聽起來像是正則表達式的情況下：

從http://weblogs.asp.net/jgalloway/archive/2004/02/11/71188.aspx

using System.Text.RegularExpressions; 

string myString = "find Me and replace ME"; 
string strReplace = "me"; 

myString = Regex.Replace(myString, "me", strReplace, RegexOptions.IgnoreCase); 

Answer 2

Dim str As String = "I am testing and testing and testing" 
    str = str.Replace("and", "or") 

Answer 3

儘管使用正則表達式的，由馬特和RQDQ的建議，你可以使用VB糖，像：

Replace(expression, find, replacement, start, count, compare)
