To fix the problem, we need to add the readonly modifier to the adminUserName field. This will ensure that the field cannot be modified after the object has been initialized, thus preventing unintended assignments and improving code safety.
- Locate the declaration of the
adminUserNamefield in theIndexModelclass. - Add the
readonlymodifier to the field declaration.

Inefficient use of ContainsKey Note

To fix the problem, we should replace the use of ContainsKey followed by an indexer operation with a single call to TryGetValue. This change will make the code more efficient by reducing the number of operations on the dictionary.
- We will modify the code on line 22 to use
TryGetValueinstead ofContainsKey. - We will introduce a new variable to hold the value retrieved by
TryGetValue. - If the key "drive" is found, we will use the retrieved value; otherwise, we will use the default value "C".

Log entries created from user input High

To fix the problem, we need to sanitize the user input before logging it. Since the log entries are plain text, we should remove any line breaks from the user input to prevent log forgery. We can use the String.Replace method to achieve this. Specifically, we will replace any occurrences of Environment.NewLine and "\n" with an empty string in the drive variable before using it to construct the str variable.
