No braces don't effect runtime performance at all. They are a language
thing and don't survive the compilation to IL code.
Write a class with these methods...
public void foo()
{
for (int i = 0; i < 100000; ++i)
Console.WriteLine("foo");
}
public void bar()
{
for (int i = 0; i < 100000; ++i)
{
Console.WriteLine("bar");
}
}
Run ildams.exe and load your assembly. Inspect the methods and notice
that exactly the same IL is produced. That code is compiled into native
x86 instructions at runtime so given the same IL the same x86
instructions should be generated and the code for both methods should be
the same.
