Enhance String Validation in Conditional Statements

[mattcobb0404]

This pull request modifies the conditional statement from If ($RetrievedRegistrationToken = "") to If ([string]::IsNullOrWhitespace($RetrievedRegistrationToken)) in order to enhance readability and accuracy.

Why the Change?

The original conditional statement If ($RetrievedRegistrationToken = "") checks for an empty string, denoted by "". However, this approach doesn't cover cases where the string might contain spaces. By using [string]::IsNullOrWhitespace($RetrievedRegistrationToken), we ensure that the condition evaluates to true not only for empty strings but also for strings containing only whitespace characters, such as spaces or tabs.

Notable Differences:

• Handling White Spaces: With the proposed change, the condition correctly evaluates a string containing only white spaces as empty, ensuring more robust behavior.
• Code Readability: The updated condition explicitly communicates the intention of checking for null or whitespace, enhancing code readability and maintainability.

Impact:

This change affects the behavior of conditional checks involving the $RetrievedRegistrationToken variable. However, it improves the accuracy of these checks by encompassing a broader range of cases.

Example:

# Original code
If ($RetrievedRegistrationToken = "") {
    # Code block
}

# Updated code
If ([string]::IsNullOrWhitespace($RetrievedRegistrationToken)) {
    # Code block
}

Additional Notes:

In the proposed change, the condition evaluates to true not only for an empty string "" but also for strings containing only white spaces.

This pull request aims to enhance the accuracy and readability of the codebase by adopting a more comprehensive approach to string validation. Please review and merge as appropriate.
