NoSpaceAfterSemicolon

Summary

A semicolon must be followed by a white space.

Default severity

Warning

Description

In most cases, a semicolon is followed by the end of the line (EOL). If exceptionally a semicolon is followed by other than EOL (e.g. an expression in a for statement, a comment, and so on), it must be followed by a space.

However, in the style like infinite for loops, semicolons may not be followed by a space, as follows:

for (;;)
{
    ...
}

Note that this analyzer and the SpaceBeforeSemicolon 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 inserting a space after the semicolon.

Example

Diagnostic

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

Code fix

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