推荐答案

上执行此操作，您将要对字符串使用IndexOf函数。这将告诉您所要查找的单词，字符等的起始字符位置。

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.

以下是示例控制台应用程序：

Here is an example console app:

    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();

    }

这将输出：

15
寻找

This will output:
15
looking for
