用`＆＃39;`替换出现的NSString到`\＆＃39;`

Question

我有一个NSString，我试图替换特殊字符。我的部分字符串如下所示：

我已将'替换为\'

Answer 1

注意： \是目标c中的转义字符。

 NSString *s = @"This is Testing Mode and we are testing just Details of this Ladies' Market place";


NSString *r = [s stringByReplacingOccurrencesOfString:@"'" withString:@"\\'"];

Answer 2

NSString *str = @"'Hello'";
str = [str stringByReplacingOccurrencesOfString:@"'" withString:@"\\"];

Answer 3

public class Foo
{
public string MemberId {get; set;} 
public string Email {get; set;} 
public string Name {get; set;} 
public string RedirectUrl {get; set;} 
}
public ActionResult SendNotification(Foo foo)

使用转义字符＆＃34; \＆＃34;，我们可以删除不需要的字符。转义字符旁边的字符（＆＃34; \＆＃34;）将被忽略/转义。
