Why is this an issue?
Empty statements represented by a semicolon ;
are statements that do not perform any operation. They are often the result of a typo or
a misunderstanding of the language syntax. It is a good practice to remove empty statements since they don’t add value and lead to confusion and
errors.
Code examples
Noncompliant code example
void DoSomething()
{
; // Noncompliant - was used as a kind of TODO marker
}
void DoSomethingElse()
{
Console.WriteLine("Hello, world!");; // Noncompliant - double ;
// ...
// Rarely, they are used on purpose as the body of a loop. It is a bad practice to
// have side-effects outside of the loop:
for (int i = 0; i < 3; Console.WriteLine(i), i++); // Noncompliant
// ...
}
Compliant solution
void DoSomething()
{
}
void DoSomethingElse()
{
Console.WriteLine("Hello, world!");
// ...
for (int i = 0; i < 3; i++)
{
Console.WriteLine(i);
}
// ...
}
