Say I have a StringBuilder object
var sb = new StringBuilder();
And an arbritrary array of strings
var s = new []{"a","b","c"};
Is this the 'quickest' way to insert them into the stringbuilder instance?
sb.Append(string.join(string.empty, s));
Or does StringBuilder have a function I have overlooked?
Edit: Sorry I dont know how many items sb will contain, or how many items may be in each String[].
If you mean by "quickest" most performant than better use:
for(int i = 0; i < myArrayLen; i++)
sb.Append(myArray[i]);
for (int i = 0; ?
string.Concat if you have array of strings.string.Concat(...) should be faster than string.Join("", ...). Also, this depends on what else you're doing with your StringBuilder. If you're only performing a few concatenations then it can be faster not to use it.
More context always helps!
Believe it or not, but string.Concat is faster than StringBuilder when the strings are 4/5.
This article discuss the question very well.
Concat method. If it is IEnumerable<string> then internally Concat uses StringBuilder class.To do this in one line without a loop, you could do this:
sb.Append(String.Join(Environment.NewLine, s));
and will also work where s is any type of
IEnumerable<string>
I believe you already have the correct answer:
sb.Append(string.join(string.empty, s))
