I was looking for the best/cleanest way to iterate over a list of strings and then create a single string of those separated by newlines (except for the last). Like so:
String 1
String 2
String 3
I have written two loops here which has a newline at the end of the string (which I want to avoid) and another that does not. The one does not just doesn't seem "clean" to me. I would think there would be a simpler way to do it so that the logic is nearly as simple as in the example that has a new line to the end of the string.
List<string> errorMessages = new List<string>();
string messages = "";
//Adds newline to last string. Unwanted.
foreach(string msg in errorMessages)
{
messages += msg + "\n";
}
messages = "";
bool first = true;
//Avoids newline on last string
foreach (string msg in errorMessages)
{
if(first)
{
first = false;
messages = msg;
}
else
{
messages += "\n" + msg;
}
}
Maybe it is wishful thinking, but I would have thought this was a common enough occurrence to warrant a better way to accomplish my goal.
