With string.StartsWith(char) and string.EndsWith(char), only the first character of the string is compared to the
provided character, whereas the string versions of those methods have to do checks about the current StringComparison and
CultureInfo. Thus, the char overloads are significantly faster for default comparison scenarios.
These overloads were introduced in .NET Core 2.0.
What is the potential impact?
We measured at least 3.5x improvement in execution time. For more details see the Benchmarks section from the More info
tab.
