``++StringBuilder++`` is more efficient than string concatenation, especially when the operator is repeated over and over as in loops.

== Noncompliant Code Example

----
string str = "";
for (int i = 0; i < arrayOfStrings.Length ; ++i) 
{
  str = str + arrayOfStrings[i];
}
----

== Compliant Solution

----
StringBuilder bld = new StringBuilder();
for (int i = 0; i < arrayOfStrings.Length; ++i) 
{
  bld.Append(arrayOfStrings[i]);
}
string str = bld.ToString();
