How do I verify that a string represents a valid ARGB value, such as #ffffffff for ARGB 255,255,255,255?
Is there a way to validate this using TypeScript and C#?

When it comes to checking if a string meets certain criteria, regular expressions can come in handy for both Typescript and C#. Below are code snippets demonstrating how to do this:
Typescript
const argbRegex = /^#[0-9a-fA-F]{8}$/;
argbRegex.test("#ffffffff"); // true
argbRegex.test("#gggggggg"); // false
C#
Regex argbRegex = new Regex("^#[0-9a-fA-F]{8}$");
argbRegex.IsMatch("#ffffffff"); // True
argbRegex.IsMatch("#gggggggg"); // False
If your goal is simply to validate that the string conforms to the 8-character ARGB format, these examples should work effectively. However, there are other considerations you may need to account for:
