问题描述
我尝试pictureBox1.Image = img;但是它很有效
I try "pictureBox1.Image = img;" but it dosent work
Cannot implicitly convert type 'System.Windows.Controls.Image' to 'System.Drawing.Image'
这个(图片img =新图片)= System.Windows.Controls.Image
This (Image img = new Image) = System.Windows.Controls.Image
private void button4_Click(object sender, EventArgs e){
GimageSearchClient client = new GimageSearchClient("http://www.google.com");
IList<IImageResult> results;
IAsyncResult result = client.BeginSearch(
textBox1.Text.Trim(), //param1
10, //param2
((arResult) => //param3
{
results = client.EndSearch(arResult);
Dispatcher.CurrentDispatcher.BeginInvoke(DispatcherPriority.Send,
(Action<IList<IImageResult>>)(async (data) =>
{
Random r = new Random();
Image img = new Image
{
Source = await DownloadImage(results[r.Next(results.Count)].TbImage.Url),
Stretch = Stretch.UniformToFill,
StretchDirection = StretchDirection.DownOnly,
};
//////// img add to Picturebox HOW ?
}), null);
}),
null //param4
);
}
推荐答案
它们不是立即兼容的,这意味着它们不能从一个转换为另一个。此链接 [ ^ ]有一些关于如何从一个转换为另一个的示例代码。
They are not immediately compatible, meaning they cannot be cast from one to the other. This Link[^] has some example code on how to convert from one to the other.
