How do I locate a particular word in a text file

I am sending mails (in asp.net ,c#), having a template in text file (.txt) like below

User Name :<User Name>

Address : <Address>.

I used to replace the words within the angle brackets in the text file using the below code

StreamReader sr;

sr = File.OpenText(HttpContext.Current.Server.MapPath(txt));

copy = sr.ReadToEnd();

sr.Close(); //close the reader

copy = copy.Replace(word.ToUpper(),"#" + word.ToUpper()); //remove the word specified UC

//save new copy into existing text file

FileInfo newText = new FileInfo(HttpContext.Current.Server.MapPath(txt));

StreamWriter newCopy = newText.CreateText();

newCopy.WriteLine(copy);

newCopy.Write(newCopy.NewLine);

newCopy.Close();

Now I have a new problem,

the user will be adding new words within an angle, say for eg, they will be adding <Salary>.

In that case i have to read out and find the word <Salary>.

In other words, I have to find all the words, that are located with the angle brackets (<>).

How do I do that?

using(StreamReader sr =File.OpenText(HttpContext.Current.Server.MapPath(txt)))
{
    copy =sr.ReadToEnd();
} // reader is closed by the end of the using block
//remove the word specified UC
copy = copy.Replace(word.ToUpper(), "#" +word.ToUpper());
//save new copy into existing text file FileInfo newText = new FileInfo(HttpContext.Current.Server.MapPath(txt));
using(var newCopy = newText.CreateText())
{
    newCopy.WriteLine(copy);
    newCopy.Write(newCopy.NewLine);
}
