已回答 在文本框中显示ini信息

[凯谢尔]

所以我所拥有的是一种布局，该布局将采用添加到文本框中的信息，然后将其添加到INI文件中。那里的所有东西都可以正常工作，但是当重新打开表单时，我希望它读取INI文件中的内容并将其显示在正确的文本框中。
我环顾四周，一无所获，但这可能也是我一直在寻找的方式。尝试过textbox.items.add（ini​​f.Read（"Database", "Devs")); with no luck.
我的代码如下
谢谢

    public partial class DashBoard : Form
    {

        public DashBoard()
        {
            InitializeComponent();
        }
       
        private void DashBoard_Load(object sender, EventArgs e)
        {

        }


        private void updatebtn_Click(object sender, EventArgs e)

            string siten = sitetxtbox.Text;
            sitetxtbox.Text = "siten";

            string personto = emailtotxtbox.Text;
            sitetxtbox.Text = "personto";

            string ccto = cctotxtbox.Text;

A TextBox only has a Text property. It does not have an Items collection. So you just need to set the Text property.

之后编辑：根据第18-28行，您似乎已经知道这一点。

As suggested, the Text property is a single string that represents all the text in the control, so you can just get your data as a string and assign it. If you need to format the text somehow then you can use a StringBuilder and then assign the final result.

Alternatively, if you have multiple strings that represent the individual lines of text then you can create a string array and assign that to the Lines property. For instance, you might create a List<string>, Add the lines to it one by one, then call ToArray and assign the result to the Lines property.
