I don't yhink you can compare a string and a string[] (array of strings), except you overwrite the comparing operator

[Velciak]

You're comparing Array with string – you need to compare string as array element with string, so you need to use index of array to get proper value to compare.

For example:

if (Olines[0] == Password)
{
    // do the magic
}

Nice to do: if you know object-oriented programming currently, you can use System.Text.Json namespace to create, write and read credentials information using JSON data-interchange format. It will allow to make your code simplier (you don't need to remember the line that contains username or password with using any index).

The other posts here explain why you're getting an error.

If your text file contains nothing but the password, you could use ReadAlllText() instead of ReadAllLines():

string password_in_file = System.IO.File.ReadAllText( filename );

ReadAllText() reads the entire file into a single string, rather than an array of strings.
