How to Re-direct Console.Writeline() messages from a dll to Winform listbox

Question

My dll has some real-time messages which are printed out using:

Console.Writeline("XYZ Message");

I have referenced this dll in my C# Windows form application. The messages are then printed out in real-time using:

public MyClientMainForm()
{
  AllocConsole();
  InitializeComponent();
}

But using this way I am launching a separate console window for displaying the messages.

Instead of a separate Console window, I wish to re-direct these messages to a Listbox inside my Winform.

Can someone help me with a simple example for this.

Answer 1

重定向Console.WriteLine到String也许是这样，您可以使用listBox1.Items.Add(stringName);将输出转换为String，然后从String转换为ListBox listBox1.Items.Add(stringName);

Answer 2

Another, probably cleaner way to do this is to extend TextWriter with your own that logs to wherever you'd like it to.

Note: I have not tested this.

public class ListBoxWriter : TextWriter
{
private ListBox list;
private StringBuilder content = new StringBuilder();

public ListBoxWriter(ListBox list)
{
    this.list = list;
}

public override void Write(char value)
{
    base.Write(value);
    content.Append(value);
    if (value == '\n')
    {
        list.Items.Add(content.ToString());
        content = new StringBuilder();
    }
}

public override Encoding Encoding
{
    get { return System.Text.Encoding.UTF8; }
}
}
