C#

I already have the file on my computer.  I do not want to read the file to my computer.  I want to read the file into an array. I did not know that the array would automatically be the right size. I do not know which of the identifiers is the array. How do I go about accessing the array.

// Read the content of the specified file into an array called "data":
byte[] data = File.ReadAllBytes("C:\Folder\TheFileToRead.ext");

for (int index = 0; index < data.Length; index++)
{
    // Access the array:
    byte theByteAtThisIndex = data[index];
    
    ...
}

byte[] data = File.ReadAllBytes("C:\Folder\TheFileToRead.ext");
BitArray dataAsBits = new BitArray(data);

Ideally what I am trying to do is copy of a file off my desktop in an Array of Bits (not Bytes).  Can you please explain how this can be done?

Are programmers do it by setting readonly property of controls true/false? Or there are other options available?

Can this be clarified a little please? There are a few different potential problems here. First off, what do you mean by "no one can edit the record"? The database admin is going to be able to edit the record, one way or another. If you mean users should not be able to edit the record, then you are in control of what they do in the application, so you must have enabled the ability to updated? I don't know why searching alters the record (as your comment seems to suggest) - this sounds like something is very wonky to me, or you don't mean database record. It might be better to expand on your question.

• Extract the UI that allows viewing/adding/updating the record as a control.
• Set the control from above's enabled state to false - this will disable the control
• Show/hide buttons in the control as appropriate


Another option is to create two controls - one for add/edit the other for view only and display the relevant one. Depending on what you are doing, you can usually improve the user experience, though at the cost of extra work, so you need to balance these off with eachother.

Are there any option available via Sql, when user find the record, the find function should call a function which fetch data from MySql Db in read-only mode.
