Example of how to operate word in C#

This article mainly introduces the method of operating word in C#, and analyzes C#'s related operating skills for reading, writing, and saving word documents in the form of examples. Friends in need can refer to this article

The example describes the method of operating word in C#. Share it with everyone for your reference, the details are as follows:

    textString = textString.Replace("/a","");  //替换空串为空。（word中/a代表空串，但在C#中，代表响铃 晕～～）否则显示控制台程序时会响
    textString = textString.Replace("/r","/n");  //替换回车为回车换行
