You need to escape the double-quotes inside the search string, like this:
您需要转义搜索字符串中的双引号，如下所示：
string orig = "\"Text\",\"Text\",\"Text\"";
string res = orig.Replace("\",\"", ";");
Note that the replacement does not occur "in place", because .NET strings are immutable. The original string will remain the same after the call; only the returned string reswill have the replacements.
请注意，替换不会“就地”发生，因为 .NET 字符串是不可变的。调用后原始字符串将保持不变；只有返回的字符串res才会有替换。

you cant use string.replace..as one string is assigned you cannot manipulate.for that we use string builder.here is my example.In html page I add [Name] which is replaced by Name.make sure [Name] is unique or u can give any unique name
你不能使用 string.replace ..因为一个字符串被分配你不能操作。为此我们使用字符串构建器。这是我的例子。在 html 页面中，我添加了 [Name]，它被 Name 替换。确保 [Name] 是唯一的或者你可以给任何唯一的名字
string Name = txtname.Text;
string contents = File.ReadAllText(Server.MapPath("~/Admin/invoice.html"));
StringBuilder builder = new StringBuilder(contents);
builder.Replace("[Name]", Name);
StringReader sr = new StringReader(builder.ToString());

set your Textbox Value in a String Like :
在字符串中设置您的文本框值，例如：

then replace your string , For Exam Replace Text To Hex :
然后替换您的字符串，对于考试将文本替换为十六进制：
MyString = MyString.Replace("Text","Hex");
Or For Your Problem (Replace "," With ;) :
或者对于您的问题（将“，”替换为;）：
MyString = MyString.Replace(@""",""",",");
Note : If You Have "" In Your String You Have to use @ In Back Of "" Like :
注意：如果您的字符串中有“”，则必须在“”后面使用@，例如：
@"","";
