I wanted to know if it is possible to obtain the path of a file which is listed in a combo, I mean, I've put the following code to list the name of the files in a folder in a combo:

DirectoryInfo d = new DirectoryInfo("1.76");
FileInfo[] files = d.GetFiles("*.bin");
comboBoxEdit1.Properties.Items.Clear();
comboBoxEdit1.Properties.Items.AddRange(files);

And now my question is, can I get the address of that file?

I would not use a case because I want to be able to introduce new files.

Try doing it comboBoxEdit1.SelectedIndex. in this way but I ran out of ideas on how to do the rest.

Another thing I think is to get the name of the selected object and make a comparison with the list of files in the folder and if it matches one get that address from that file and that it does in a variable, the problem is that I have the idea but I would not know how to do the code.

I think what I'm asking is impossible to do, but if someone knows how to do it, I'd really appreciate it if you could explain how, thanks.

Use the Datasource property

 DirectoryInfo d = new DirectoryInfo("1.76");
        FileInfo[] files = d.GetFiles("*.bin");
        comboBoxEdit1.DataSource = files;
        comboBoxEdit1.DisplayMember=nameof(FileInfo.Name);

The selected object will be a FileInfo, with all its properties

If you are using the ComboBox that comes by default in Visual Studio to work with Windows Forms, that is, the one included in the .NET Framework: System.Windows.Forms.ComboBox , it does not have a Properties property. I suppose it will be an error to copy the load code of the ComboBox. It should be:

DirectoryInfo d = new DirectoryInfo(@"C:\Windows");
FileInfo[] files = d.GetFiles("*.bin");
comboBoxEdit1.Items.Clear();
comboBoxEdit1.Items.AddRange(files);

If you load the ComboBox in this way, the SelectedItem property of this will return a FileInfo object with the information of the selected element. Through the property FullName of the object FileInfo you can access the full path of the file:

private void comboBoxEdit1_SelectedIndexChanged(object sender, EventArgs e)
{
    var file = (FileInfo)comboBoxEdit1.SelectedItem;
    Debug.WriteLine(file.FullName);
}
