新Form AllowDrop True

引用using System.IO;

拖1个Button

public Form1()
{
InitializeComponent();
}

string fileName;
String extendedName;
String fileName1;

private void button1_Click(object sender, EventArgs e)
{
OpenFileDialog ofd = new OpenFileDialog();                //new一个方法
ofd.InitialDirectory = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments); //定义打开的默认文件夹位置
ofd.ShowDialog();          //显示打开文件的窗口
fileName = ofd.FileName;                //获得选择的文件路径
extendedName = Path.GetExtension(fileName);       //获得文件扩展名
fileName1 = Path.GetFileName(fileName);

PlayFlash f = new PlayFlash(fileName);
f.Show();

}

//拖入

private void Form1_DragEnter(object sender, DragEventArgs e)
{
if (e.Data.GetDataPresent(DataFormats.FileDrop))
{
e.Effect = DragDropEffects.Copy;
}
}

//拖入操作释放

private void Form1_DragDrop(object sender, DragEventArgs e)
{
if (e.Data.GetDataPresent(DataFormats.FileDrop))
{
string[] MyFiles = (string[])(e.Data.GetData(DataFormats.FileDrop));
if (MyFiles.Length > 0)
{
PlayFlash f = new PlayFlash(MyFiles[0]);//播放窗体传值
f.Show();//播放窗体显示
}
}
}

新建Form

拉一个webBrowser

拖1个timer

设计Form背景为透明等属性

/// <summary>
/// 存放Flash路径
/// </summary>
string playFile = "";

public string Isplay;

/// <summary>
/// 获取Flash路径并渲染窗体
/// </summary>
/// <param name="file"></param>
public Form1(string file)
{
playFile = file;
InitializeComponent();
}

private void Form1_Load(object sender, EventArgs e)
{
//新的文档
webBrowser1.Navigate("about:blank");

//判断文档是否在加载
while (webBrowser1.IsBusy)
{
Application.DoEvents();
}

webBrowser1.Document.Write("<HTML>");
webBrowser1.Document.Write("<HEAD>");
webBrowser1.Document.Write("<TITLE>");
webBrowser1.Document.Write("</TITLE>");
webBrowser1.Document.Write("<script type='text/javascript' language='javascript'>");
webBrowser1.Document.Write("function a() {");
webBrowser1.Document.Write("var ab= document.swf.IsPlaying();");
webBrowser1.Document.Write("var d = document.getElementById('xxx');");
webBrowser1.Document.Write("d.value = ab;");
webBrowser1.Document.Write(" }");
webBrowser1.Document.Write("</script>");
webBrowser1.Document.Write("</HEAD>");
webBrowser1.Document.Write("<BODY>");
//网页效果输出Flahs
webBrowser1.Document.Write(string.Format("<object classid=\"clsid:D27CDB6E-AE6D-11cf-96B8-444553540000\" width=\"100%\" height=\"100%\" id=\"swf\"> <param name=\"wmode\" value=\"transparent\"><param name=\"movie\" value=\"{0}\"> <param name=\"quality\" value=\"high\"><param name=\"LOOP\" value=\"false\" /></object>", playFile));
webBrowser1.Document.Write("<input id=\"xxx\" type=\"hidden\" runat=\"server\" /></BODY>");
webBrowser1.Document.Write("</HTML>");

timer1.Interval = 50;
timer1.Enabled = true;

}

int sum = 0;

private void timer1_Tick(object sender, EventArgs e)
{
webBrowser1.Document.InvokeScript("a");

Isplay = webBrowser1.Document.All["xxx"].GetAttribute("value");
if (Isplay == "false")
{
timer1.Enabled = false;
this.Close();
}
sum = sum + 1;
if (sum > 100)
{
timer1.Enabled = false;
this.Close();
}
}
