如何在文本框中显示字符串数组？

Question

private void SplitString()
{
    ArrayList splitted = new ArrayList();

    string[] words = richTextBox1.Text.Split(new char [] { ' ' },
    StringSplitOptions.RemoveEmptyEntries);

    var word_query =
        (from string word in words
         orderby word
         select word).Distinct();

    string[] result = word_query.ToArray();

    foreach(string results in result)
    {
        richTextBox2.Text = results;
    }         
}

I wrote a form application for taking a text file and splitting strings at the file. And the final purpose is writing unique strings on textbox. The problem is strings flow quickly on textbox but i like to stand them on textbox.

Answer 1

You are iterating your array and assigning each time so textbox will have only last item of the array.

You just to join your array and display in the textbox in following way :

string[] result = word_query.ToArray();
richTextBox2.Text = String.Join(",",result); // You can use any string as separator.

Answer 2

如果希望每个字符串在文本框中都显示在单独的行上，只需将字符串数组分配给Lines属性，如下所示：

richTextBox2.Lines = result;
