Create a comma-separated strings in C#

Question

I have an object which holds many values, and some of them (not all values from the object) need to be put in a CSV string. My approach was this:

string csvString = o.number + "," + o.id + "," + o.whatever ....

Is there is a better, more elegant way?

Answer 1

If you put all your values in an array, at least you can use string.Join.

string[] myValues = new string[] { ... };
string csvString = string.Join(",", myValues);

You can also use the overload of string.Join that takes params string as the second parameter like this:

string csvString = string.Join(",", value1, value2, value3, ...);
