namespace abc

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }
    EmoticonRender ab = new EmoticonRender();
    private void button1_Click(object sender, EventArgs e)
    {
        string textie = ab.Parse(textBox1.Text);
        richTextBox1.Text += textie+"\n";
    }
}
public class EmoticonRender
{

    private List<KeyValuePair<string, string>> _dictionary = new List<KeyValuePair<string, string>>() 
    {
    new KeyValuePair<string, string>(":-)", "a.png"),
    new KeyValuePair<string, string>(";-(", "a.png"),
    };

    public string Parse(string text)
    {
    foreach(KeyValuePair<string, string> kvp in _dictionary)
    {
    text = text.Replace(kvp.Key, @"C:\Users\Buddiez\Documents\Visual Studio 2010\Projects\abc\abc\a.png");
    }
    return text;
    }

}

}

我使用这些代码行将笑脸插入到 Richtextbox 中，但不是显示笑脸，而是显示 png imgae 的路径，即。 C:\Users\Buddiez\Documents\Visual Studio 2010\Projects\abc\abc\a.png

Answer 1

复制您拥有的所有图像并导航到 >> Visual Studio 选择 Project>>Properties.There 选择 Resources 并将所有复制的图像粘贴到右侧 Pane 中。

    Hashtable emotions;
    void CreateEmotions()
    {
        emotions= new Hashtable(6);
        emotions.Add(":-)", Project.Properties.Resources.regular_smile);
        emotions.Add(":)",  Project.Properties.Resources.regular_smile);

    }

    void AddEmotions()
    {
        foreach (string emote in emotions.Keys)
        {
            while(richTextBox1.Text.Contains(emote))
            {
                int ind = richTextBox1.Text.IndexOf(emote);
                richTextBox1.Select(ind, emote.Length);
                Clipboard.SetImage((Image)emotions[emote]);
                richTextBox1.Paste();
            }
        }
    }
