Hi

I have a vb application that passes a file name (a string that defines the full path for a file) to a C# DLL. I verified that the string is being passed fine. Problem is that as soon as I try to do this:

FileInfo fiFile = new FileInfo(inFile);

I get this exception:

C# Exception: Request for the permission of type System.Security.Permissions.FileIOPermission, mscorlib, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 failed.
C# Exception: at System.Security.CodeAccessSecurityEngine.CheckHelper(PermissionSet grantedSet, PermissionSet deniedSet, CodeAccessPermission demand, PermissionToken permToken)

C# Exception:
C# Exception: Thrown ByVoid CheckHelper(System.Security.PermissionSet, System.Security.PermissionSet, System.Security.CodeAccessPermission, System.Security.PermissionToken)



I tried adding this

int inFilePathMarker = inFile.LastIndexOf('\\');
string inFilePath = inFile.Substring(0,inFilePathMarker - 2);
FileIOPermission filePerm = new FileIOPermission(FileIOPermissionAccess.Read, inFilePath);
FileInfo fiFile = new FileInfo(inFile);


But this still did me no good.

I am using the VS IDE to compile and link the DLL and I can see that the assembly was registered.

I need the dll to be used by the general public. I am hoping that I won't have to hard code the inFile in my dll
:-\ :-\
