Question

I am initialising a StringBuilder as follows:

StringBuilder builder = new StringBuilder("Symptoms are ");

After this I loop through a list and add each string item to the end using

foreach(var item in list)
{
    builder.Append(item);
}

An example item would be something like “headache” but once i’ve appended it to “Symptoms are ” and called builder.ToString() it shows:

"Symptoms areHeadache...etc"

as opposed to

"Symptoms are Headache...etc"

Why is it ignoring the space?

Answer 1

Since the code you’ve provided doesn’t produce the problem you’ve described, I’m guessing that your actual problem is a lack of whitespace between the symptoms (items). In that case, I’d suggest using String.Join() like so:

var output = String.Format("Symptoms are {0}.", String.Join(", ", items));

Now your items will be comma-separated with a padding space between.
