Form1加载事件只执行第一条语句

Question

在我的Form1事件中，并不是所有的事情都完成了。实际上只执行了第一行。

private void Form1_Load(object sender, EventArgs e)
    {
        //Save the currentUser text document's contents into the currentUser string
        System.IO.StreamReader file = new System.IO.StreamReader("C\Users\WoopyCat\AppData\Roaming\.minecraft\currentUser.txt");
        currentUser = file.ReadLine();
        //Save the currentUser into the textbox
        TBcurrentUser.Text = "The current user is " + currentUser + ".";
        //Set the default text for the textbox
        TBchangeTo.Text = "Whose Minecraft folder are you switching to?";
        //Add the default two items to the listbox
        LBfiles.Items.Add("Minecraft folders:" + Environment.NewLine);
        LBfiles.Items.Add("---------------------------------------------------------------------------------------------------------------------------");
        //Create the directory if it doesn't exist
        if (!Directory.Exists("C:\Users\WoopyCat\AppData\Roaming\" + folderName))
        {
            Directory.CreateDirectory("C:\Users\WoopyCat\AppData\Roaming\" + folderName);
        }
        //Set the default instructions in the textbox
        TBinstructions.Text = instructions;
        //Add each directory to the listbox
        foreach (string value in Directory.GetDirectories("C:\Users\WoopyCat\AppData\Roaming\" + folderName))
        {
            //Remove the file location from the string
            each = value.Replace("C:\Users\WoopyCat\AppData\Roaming\.MCSwitcher\", "");
            LBfiles.Items.Add(each + Environment.NewLine);
        }
    }

加载表单时不会发生任何事情。如果我添加第一行，那么它实际上发生了。就像如果我把一个消息框作为这个事件的第一行，它就会发生。但这段代码中没有任何内容。

更改

System.IO.StreamReader file = new System.IO.StreamReader("C\Users\WoopyCat\AppData\Roaming\.minecraft\currentUser.txt");

至

System.IO.StreamReader file = new System.IO.StreamReader("C:\Users\WoopyCat\AppData\Roaming\.minecraft\currentUser.txt");

您忘记了冒号
