C# String Replace

问题:

I want to replace "," with a ; in my string.

For Example:

Change this

"Text","Text","Text",

to this

"Text;Text;Text",

I've been trying the line.replace( ... , ... ) but can't get anything working properly.

Any help would be appreciated.

回答1:

Have you tried this:

line.Replace("\",\"", ";")

回答2:

You need to escape the double-quotes inside the search string, like this:

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 res will have the replacements.

回答3:

var str = "Text\",\"Text\",\"Text";
var newstr = str.Replace("\",\"",";");

回答4:

The simplest way is to do

line.Replace(@",", @";");

Output is shown as below:

Make sure you properly escape the quotes.

  string line = "\"Text\",\"Text\",\"Text\",";

  string result = line.Replace("\",\"", ";");

回答8:

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

    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());
