需要得到一个&QUOT后的字符串;字QUOT;在C＃中的字符串 [英] Need to get a string after a "word" in a string in c#

问题描述

我遇到在C＃中的字符串，我有字符串中查找特定的单词代码，并必须得到单词码后剩余的字符串。

的字符串是

错误描述，代码：-1

所以我必须找到在上面的串词的代码，我必须得到错误代码。
我已经看到了正则表达式，但现在明确的理解。有没有简单的方法

解决方案

 字符串tobesearched =代码：？
串码= myString.Substring（myString.IndexOf（tobesearched）+ tobesearched.Length）; 
  

这样呢？

也许你应处理失踪代码的情况： ...

 字符串tobesearched =代码：
 INT九= myString.IndexOf（tobesearched）; 
 
如果（！九= -1）
 {
串码= myString.Substring（IX + tobesearched.Length）; 
 //做的东西在这里
} 
  

i'm having a string in c# for which i have to find a specific word "code" in the string and have to get the remaining string after the word "code".

The string is

"Error description, code : -1"

so i have to find the word code in the above string and i have to get the error code. I have seen regex but now clearly understood. Is there any simple way ?

解决方案

string tobesearched = "code : "
string code = myString.Substring(myString.IndexOf(tobesearched) + tobesearched.Length);

Something like this?

Perhaps you should handle the case of missing code :...

string tobesearched = "code : "
int ix = myString.IndexOf(tobesearched);

if (ix != -1) 
{
    string code = myString.Substring(ix + tobesearched.Length);
    // do something here
}
