Question

I have a variable “StudentID” which is an int, I need to convert to a string then pass it to string as a string.

This is what I have so far:

int StuID = Convert.ToString("StudentID");

string ReturnXML = "<Student=\"StuID\" />";

So if the “StudentID” variable were equal to 12345, I need the ReturnXML to look like this:

<Student="12345">

Any suggestions?

Answer 1

I took the liberty to alter the XML a bit, to make it valid.

int studentId = 42;
string returnXml = string.Format(@"<Student id=""{0}"" />", studentId);
// returnXml will be '<Student id="42" />'

If you want the Student element itself to have the student id value, you probably want to put the value inside the element:

string returnXml = string.Format(@"<Student>{0}</Student>", studentId);
// returnXml will be '<Student>42</Student>'
