String str1 = content. Replace ("&","&");
String str2 = str1.Replace (""","\"");
String str3 = str2.Replace ("<br>", "\ r \ n ");

This is used for SQL escape character conversion. At first, we found that only the first one was converted. At that time, I was depressed. In the dumbest way, I made two loops to replace the others. Later, you can change it to string str1 = content. Replace/& amp;/g, "&"); to Replace all.
