Question

我在这里粘贴了代码，用于在wpf C＃中创建html文件。所以请帮我打印那个文件。在下面的代码中，我创建了一个html字符串，并将该html文件保存到代码中给出的路径中。现在我想直接将这个文件转到打印对话框，这样我就可以打印html文件了。

private void Button_Click_1(object sender, RoutedEventArgs e) {
        string path = @"C:\Users\EACD-017\Documents\Host.html";
        string HTML =   "<html>" +
                        "<head>" +
                        "<title>"+
                         "   HOST INFORMATION " +
                        "</title>" +
                        //"    <style type=\"text/css\">" +
                        //"    .title {" +
                        //"        color: blue;" +
                        //"        text-decoration: bold;" +
                        //"        text-size: 1em;" +
                        //"    }" +

                        //"        border:1px;" +

        System.IO.File.AppendAllText(path,HTML);

        MessageBox.Show("Document created successfully !");
    }

Answer 1

这应该这样做。

private void PrintDocument(Uri uri)
{
    var wb = new System.Windows.Forms.WebBrowser();
    wb.DocumentCompleted += PageLoaded;
    wb.Url = uri;
}

private void PageLoaded(object sender, WebBrowserDocumentCompletedEventArgs e)
{
    ((System.Windows.Forms.WebBrowser)sender).Print();
}

private void Button_Click_1(object sender, RoutedEventArgs e)
{
    var url = new Uri(@"C:\Users\EACD-017\Documents\Host.html");
    PrintDocument(url);
}

Answer 2

以下代码应以给定文件作为参数打开IEXPLORE.exe。

Process process = new Process();
process.StartInfo.FileName = "iexplore.exe";
process.StartInfo.Verb = "runas";
process.StartInfo.Arguments = "PATH/TO/YOUR/FILE.HTML";
process.Start();

但首先，在HTML内容中，您应该添加以下代码以在启动时打印：

<script type="text/javascript">
    window.onload = function () {
        window.print();
    }
</script>
