Decompiler - Local names are incorrectly mapped from a pdb file

created 9 years ago (modified 9 years ago)

Decompile code:

C#
public void Bar(int argument) { if(argument < 0) throw new ArgumentException("Blah", "argument"); double cathetus1 = 3; double cathetus2 = 4; double hypotenuse = Sqrt(cathetus1 * cathetus1 + cathetus2 * cathetus2); }

decompiled code is:

C#
public void Bar(int argument) { bool cathetus1; cathetus1 = argument < 0; if (cathetus1) { throw new ArgumentException("Blah", "argument"); } double cathetus2; cathetus2 = 3D; double hypotenuse; hypotenuse = 4D; double sqrt; sqrt = Math.Sqrt(cathetus2 * cathetus2 + hypotenuse * hypotenuse); }

You can see inserted temporal local took name from the pdb file

Another example - exception variable also steals local name:

C#
public void Bar(int argument) { int first = 11; try { throw new Exception("aa"); } catch(Exception ex) when (ex.Message.Contains("a")) { } int second = 22; }

Decompiled version:

C#
public void Bar(int argument) { int first; first = 11; try { throw new Exception("aa"); } catch (Exception second) when (second.Message.Contains("a")) { } int intNum; intNum = 22; }
