推荐答案

您可以使用File.ReadAllLines("file path").Length.这将为您提供文件中的行数.

You can us File.ReadAllLines("file path").Length. This will give you the number of lines in the file.

将文件加载到字符串中并按如下方式拆分-
string [] array = file.Split(new char [] {''\ n''});

数组的计数将为您提供字符串数.

Load the file into a string and split as follows -
string[] array = file.Split(new char[]{''\n''} );

The count of array would give you the number of strings.
