Extern member cannot declare a body

• Apr 29, 2019

CodeRush Classic shows the Extern member cannot declare a body code issue if an extern member declares a body.

Fix

Remove the extern method body.

Purpose

Highlights the extern method declaration statements, which would cause the Cannot be extern and declare a body compilation error.

Example

C#

[DllImport("user32.dll")]
static extern int │DrawText(IntPtr hDC, string lpString, int nCount, ref Rect lpRect, uint uFormat)
{

}

Fix:

C#

[DllImport("user32.dll")]
static extern int DrawText(IntPtr hDC, string lpString, int nCount, ref Rect lpRect, uint uFormat);
