using LinkDotNet.StringBuilder; // Namespace of the package
ValueStringBuilder stringBuilder = new ValueStringBuilder();
stringBuilder.AppendLine("Hello World");
string result = stringBuilder.ToString();
There are also smaller helper functions, which enables you to use ValueStringBuilder without any instance:
The dotnet version of the StringBuilder is a all purpose version which normally fits a wide variety of needs.
But sometimes low allocation is key. Therefore I created the ValueStringBuilder. It is not a class but a which tries to do as less allocations as possible.
If you want to know how the works and why it uses allocations and is even faster, checkout blog post.
The blog goes a bit more in detail how it works with a simplistic version of the .
The library is not meant as a general replacement for the StringBuilder shipped with the .net framework itself. You can head over to the documentation and read about the "Known limitations".
The library works best for a small to medium amount of strings (not multiple 100'000 characters, even though it can be still faster and uses less allocations). At anytime you can convert the ValueStringBuilder to a "normal" StringBuilder and vice versa.
The normal use case is to add concatenate strings in a hot-path where the goal is to put as minimal pressure on the GC as possible.
Documentation
A more detailed documentation can be found here. It is really important to understand how the ValueStringBuilder works so that you not run into weird situations where performance / allocations can even rise.
Benchmark
The following table gives you a small comparison between the StringBuilder which is part of .NET, ZString and the ValueStringBuilder:
