SpaceBeforeSemicolon

Summary

A semicolon must not be preceded by a white space.

Default severity

Warning

Description

In general, semicolons are not preceded by a space.

Note that this analyzer and the NoSpaceAfterSemicolon analyzer are intended to be used together and replace SA1002 with them, allowing us to write an infinite for loop with for (;;).

Code fix

The code fix provides an option eliminating spaces before the semicolon.

Example

Diagnostic

public void Method()
{
    var n = 10 ;
    Console.WriteLine() /**/ ;
    for (var k = 0 ; k < n ; ++k)
    {
    }
    for ( ; ;)
    {
        return
        ;
    }
}

Code fix

public void Method()
{
    var n = 10;
    Console.WriteLine() /**/;
    for (var k = 0; k < n; ++k)
    {
    }
    for (;;)
    {
        return;
    }
}
