How to get INDEX of word inside a string
提问by Bryan Arbelo - MaG3Stican
I am trying to get the INDEX of a word inside a string and if possible also to delete all the characters previous to this word in the string, it would make my life easier.
我正在尝试获取字符串中某个单词的 INDEX，如果可能还删除字符串中该单词之前的所有字符，这将使我的生活更轻松。
Could anyone help me? Im doing this on c#

You'll want to use the IndexOf function on a string. This will tell you the starting character position of the word, character, etc that you're looking for.
您需要在字符串上使用 IndexOf 函数。这将告诉您要查找的单词、字符等的起始字符位置。
Here is an example console app:
这是一个示例控制台应用程序：
static void Main(string[] args)
{
String testing = "text that i am looking for";
Console.Write(testing.IndexOf("looking") + Environment.NewLine);
Console.WriteLine(testing.Substring(testing.IndexOf("looking")));
Console.ReadKey();
}
This will output:
15
looking for
这将输出：
15
寻找

Yes, you can use Substring to delete all the characters previous
是的，您可以使用 Substring 删除之前的所有字符
string str = "I'm stuck here please help, something else....yyyy";
string output = str.Substring(str.IndexOf("help"));
WriteLine($"Output string value :{output}");//help,something else....yyyy
