Your question is not clear. What do you want to do?

"1. I did not ask this question.
2. If you need any clarifications, make use of comments section. Do not post that as solutions. " -Whoops my bad. I deleted it.

You should try to use conditions instead to check Member11280947. For example, have some validation routine and set a boolean flag to false/true based on it.
Anyway the solution to this is to either convert the input to upper or lower case and validate it accordingly or you could choose the inbuilt static method string.compare as listed in MSDN <https: msdn.microsoft.com="" en-us="" library="" zkcaxw5y(v="vs.110).aspx">.

This is definitely not a good way to check for permissions.

To compare the strings, you can make use of

C#

string.Compare(string1,string2,StringComparison.OrdinalIgnoreCase)

The problem here is you are using the wrong Control for this task.

1. if you want to show a text notice to the user, that they can't interact with: use a Label.

2. use a TextBox when having the user edit the contents means something.

3. perform validation as soon as possible and keep Controls that you do not want the user to interact with disabled until using those Controls is "legal." Why let the user make a stupid mistake in the first place ?

4. consider using a UI element like a StatusBar to keep the user informed about the current state of the UI as it effects their possible choices.

Text boxes are free-form user entry fields - so it is possible for a user to enter something not quite as you expected. And we, as humans, sometimes see what we expected, not what is really there. So...
1. Perhaps there are leading / trailing spaces
2. Perhaps you are seeing 'False' when in reality the text is 'false' (F vs f)

Try the following:

if (TXTSAVE.Text.Trim().Equals("False", StringComparison.InvariantCultureIgnoreCase))
    { 
    MessageBox.Show("You Do Not Have Permission");
    return;
    }
