Weird, Stupid Problems in C#

[glut]

Here's my error.
"System.NotSupportedException"

I have some problems with the StreamReader class.

I have a textbox, and with the textbox, the text is the files location. I have tried with a pattern('@'), and with using the double slash character, and NOTHING has worked.

Here is my function

static string ReadFile(string filePath)
        {
            string ret = "";
            string line;
            StreamReader file = new StreamReader(filePath);
            while ((line = file.ReadLine()) != null)
                ret += line;
            return ret;
        }

Here's usage

textBox1.Text = ReadFile(treeView2.SelectedNode.ToString());

And it is not the treeview messing up.

If I get the text from the TreeView, and put it there, I don't get errored, lmao, so stupid.

Thanks

Here's the documentation of TreeView.SelectedNode .

Your ReadFile function works just fine, so the problem has to be in the passed argument (filePath). You could add following lines to the beginning of ReadFile:

if (filePath == null) MessageBox.Show("FilePth has null value");
if (!File.Exists(filePath)) MessageBox.Show("File: '" + filePath + "' not found");

Your "System.NotSupportedException" message could be from a null file name (= no selected node is selected). Also, is treeView2.SelectedNode.ToString() correct or do you try to get treeView2.SelectedNode.FullPath ? In the latter case your TreeView2.PathSeparator should be @"\". Just a few thoughts...

To get the path, you have to use treeView2.SelectedNode.FullPath; property.
And its a bit strange to put all the files one beside another into textBox. At lease seperate them, by using some delimiter like commma:

//selected node:
textBox1.Text = ReadFile(treeView2.SelectedNode.FullPath;

//your method
        static string ReadFile(string filePath)
        {
            string ret = "";
            string line;
            StreamReader file = new StreamReader(filePath);
            while ((line = file.ReadLine()) != null)
                ret += line + ", "; //changed to seperate files
            return ret;
        }
