You can use FindIndex

您可以使用FindIndex

 var index = Array.FindIndex(myArray, row => row.Author == "xyz");

Edit: I see you have an array of string, you can use any code to match, here an example with a simple contains:

编辑:我看到你有一个字符串数组，你可以使用任何代码来匹配，这里有一个简单的包含:

 var index = Array.FindIndex(myArray, row => row.Contains("Author='xyz'"));

Maybe you need to match using a regular expression?

也许您需要使用正则表达式进行匹配?

#2

try Array.FindIndex(myArray, x => x.Contains("author");

尝试数组。FindIndex(myArray x = > x.Contains(“作者”);

#3

The previous answers will only work if you know the exact value you are searching for - the question states that only a partial value is known.

之前的答案只有当你知道你正在搜索的确切值时才会起作用——问题是只知道一个部分的值。

Array.FindIndex(authors, author => author.Contains("xyz"));

This will return the index of the first item containing "xyz".

这将返回包含“xyz”的第一项的索引。

     int i=  Array.IndexOf(temp1,  temp1.Where(x=>x.Contains("abc")).FirstOrDefault());
