如何将多行文本框绑定到bindingList <string> ？

Question

How can I bind textboxt text to BindingList? I want so that when I add/change/remove string from that BindingList my TextBox will update.

Answer 1

Create a single string with line breaks from the List

 stringbuilder sb = new stringbuilder();   
 foreach (string s in lstring) sb.AppendLine(s); 

Answer 2

Use BindingSource class to bind a String to a textbox. All you need is to bind the textbox with BindingSource object, whose data source is the string you want to use.

TextBox textBox1 = new TextBox();
BindingSource stringBindingSource;
string x = "ABCDEFGHIJKLMNOP";

stringBindingSource = new System.Windows.Forms.BindingSource(this.components);
textBox1.DataBindings.Add(new Binding("Text",stringBindingSource,"Length",true));
stringBindingSource.DataSource = x;
