示例1: RewritePostfixUnarys

{
if (expr.Kind != SyntaxKind.PostIncrementExpression && expr.Kind != SyntaxKind.PostDecrementExpression)
continue; // These aren't the droids we're looking for.
IdentifierNameSyntax name = FindIdentifierName (expr);
if (name == null)

{
var newExpr = GetLogExpression (name.PlainName, expr);
