如何用图像替换文本 [英] How to replace a text with an image

问题描述

private void txtLog_TextChanged(object sender, EventArgs e)
        {
            Image img = Image.FromFile("C:/Dokumente und Einstellungen/mgmeiner/Desktop/smile3.gif");
            string smile1 = ":)";
            if (txtLog.Text.Contains(smile1))
            {
                txtLog.Text = txtLog.Text.Replace(":)", Clipboard.SetImage(img));
            }
        }

但这不起作用！

But this doesn''t work!

推荐答案

那是因为它是一个文本框，而不是图像的默认占位符.您将不得不自己绘制控件，当遇到序列":)"时，您不会绘制字母，而是绘制图像.除了简单地用图像替换文本序列以外，还有很多工作要做.现在，您要混合使用不同的类型.

但是，您可以使用已经具有实现功能的rtf控件，请在此处查看:

祝你好运！

That''s because it''s a textbox and not a default placeholder for images. You would have to draw the control yourself and when you encounter the sequence ":)" you wouldn''t draw the letters but the image instead. There is some more work to it than simply replacing a text sequence by an image. You are now mixing different types that do not apply.

You could however use an rtf control that already has implementation for this, have a look here:

Good luck!
