Unable to create instance of class
TestClass. Error:

Test_Library.cs:

public string[] GetAutoConfig()
{
    FileStream fs = new FileStream(sConfigFile, FileMode.Open);  // line 40
    StreamReader sr = new StreamReader(fs);
    string line = "";
    string[] arrline = new string[2];
}

TestClass.cs:

arrConfig = KMLib.GetAutoConfig(); // line 33

Why am I getting this error? I made sure that the folder is shared to everyone, and removed the Read Only.

Answer 1

You’re getting this error because as the exception message says the current user doesn’t have access to the file in question. You need to adjust the permissions of that file and it’s parent directories to allow access to the user in question

Part of the problem is your choice of location. It looks like you are attempting to share a configuration file between a set of users yet you’ve chosen the location of the document to be under the Administrator directory.

C:\Documents and Settings\Administrator\My Document

If you want to share amongst users then I would use the All Users or Public directory instead as it’s meant for this type of operation.
