?new string(new char[]{'1'})
A first chance exception of type 'System.InvalidOperationException' occurred in mscorlib.dll
'new string(new char[]{'1'})' threw an exception of type 'System.InvalidOperationException'
base {System.SystemException}: {"InvalidOperationException"}
If I typed the same expression into a normal C# desktop app .Net 3.5 application, this is what I got:
?new string(new char[]{'1'})
'new string(new char[]{'1'})' threw an exception of type 'System.ArgumentException'
base {System.SystemException}: {"Only NewString function evaluation can create a new string."}
Message: "Only NewString function evaluation can create a new string."
ParamName: null
I'm exteremly puzzeled. Anyone have any ideas?

Hi,
NewString is the name of the command which is used in CorDbg. Since we are not using CorDbg, getting this exception is very silly.
I currently use a not-so-nice workaround for this.
In "Immediate Window", I create and instance of StringBuilder, append char array, and call ToString of string builder.
StringBuilder sb = new StringBuilder();
sb.Append(new char[] {'1', '2', '3'});
sb.ToString()
System.IO.File.WriteAllText( "c:\\temp\\doNotTryAtHome.txt", sb.ToString())
So that works. Using Reflector, the Append method converts the char[] to a string using some pointer magic. The String(char[]) constructor actually makes some low level call that won't show up in Reflector. Must be a bug.
It would still be nice to not have to jump through such a hoop though.
