嗨huzz，


嗯，我不完全确定这是最好的方法，但如果你知道

就有或者 "最后你可以做什么


String s =" Keywords LIKE''％awlad％''OR Keywords LIKE''％huzz％''OR" ;;

s = s.Substring（0，s.Length - " OR" .Length）;

Hi huzz,

Well, I''m not entirely sure this is the best approach, but if you know
there is "OR " at the end you could do

String s = "Keywords LIKE ''%awlad%'' OR Keywords LIKE ''%huzz%'' OR ";
s = s.Substring(0, s.Length - "OR ".Length);

> I have : "Keywords LIKE ''%awlad%'' OR Keywords LIKE ''%huzz%'' OR "

我想要：" Keywords LIKE''％awlad％''或者关键词LIKE''％huzz％''"


string s =" Keywords LIKE''％awlad％''OR Keywords LIKE''％huzz％''OR" ;;


if（s.EndsWith（" OR））

{

//第一个参数是起始索引，第二个参数是字符数。

s = s.Substring（0，s.LastIndexOf（" OR"））;

}


Debug.Print （s）;


//应该打印：关键词LIKE''％awlad％''或关键词LIKE''％huzz％''"

I want: "Keywords LIKE ''%awlad%'' OR Keywords LIKE ''%huzz%'' "
string s = "Keywords LIKE ''%awlad%'' OR Keywords LIKE ''%huzz%'' OR ";

if (s.EndsWith(" OR "))
{
// First argument is the start index, second argument is the number of characters.
s = s.Substring(0, s.LastIndexOf(" OR "));
}

Debug.Print(s);

// should print: "Keywords LIKE ''%awlad%'' OR Keywords LIKE ''%huzz%'' "
