推荐答案

试试这个

try this

txtabc.Text = "\"\"";

为了补充（完全有效）解决方案1，让我向您解释发生了什么。



由于字符串是用双引号分隔的，如果你想在字符串中使用双引号，你有两种方法可以做到这一点：



1-通过转义要放入字符串的双引号（如解决方案1）;转义字符是反斜杠（ \ ）。



2-将每个双引号加倍字符串，但是你必须使用字符串文字。因此，适应您的问题：

To complement the (perfectly valid) solution 1, let me explain you what is going on.

Since the strings are delimited by double quotes, if you want a double quote in the string you have two ways to do that:

1- By escaping the double quotes you want to put in the string (like in solution 1); escape character is backslash (\).

2- By doubling each double-quote you want in the string, but then you have to use a string literal. Thus, adapted to your question:

txtabc.Text = @"""""";

希望这会有所帮助。

Hope this helps.
