这一定是一个非常菜鸟的问题，所以请不要过分评价我！在 Windows 窗体应用程序中，这样的事情很容易获得进度条的边界：

progressBar1.Bounds.X(or)Y

如何在 WPF 中获得相同的效果？我在互联网上找不到任何东西。这是我的 windows 窗体应用程序的进度条OnClick 方法：

private void progressBar1_MouseClick(object sender, MouseEventArgs e)
{
    float absoluteMouse = (PointToClient(MousePosition).X - progressBar1.Bounds.X);
    float calcFactor = progressBar1.Width / (float)100;
    float relativeMouse = absoluteMouse / calcFactor;
    double maxlength = BASS_ChannelBytes2Seconds(BassHandle, (ulong)PlayBackLength);
    double percents = (maxlength * relativeMouse) / 100;
    UInt64 pos = BASS_ChannelSeconds2Bytes(BassHandle, percents);
    BASS_ChannelSetPosition(BassHandle, pos, 0);
    progressBar1.Value = Convert.ToInt32(relativeMouse);
    int current = BASS_ChannelGetPosition(BassHandle, 0);
    TimeLabel.Text = FormatTime(BASS_ChannelBytes2Seconds(BassHandle, (uint)current)) + "/" + FormatTime(BASS_ChannelBytes2Seconds(BassHandle, (uint)PlayBackLength));
}

这是我在WPF 版本上的尝试

private void progressBar1_MouseLeftButtonUp(object sender, MouseButtonEventArgs e)
{

    double absoluteMouse = (PointFromScreen(GetMousePosition()).X - progressBar1.?);
    double calcFactor = progressBar1.Width / (float)100;
    double relativeMouse = absoluteMouse / calcFactor;
    double maxlength = Imports.BASS_ChannelBytes2Seconds(GlobalVariables.BassHandle, (ulong)GlobalVariables.PlayBackLength);
    double percents = (maxlength * relativeMouse) / 100;
    UInt64 pos = Imports.BASS_ChannelSeconds2Bytes(GlobalVariables.BassHandle, percents);
    Imports.BASS_ChannelSetPosition(GlobalVariables.BassHandle, pos, 0);
    progressBar1.Value = Convert.ToInt32(relativeMouse);
    int current = Imports.BASS_ChannelGetPosition(GlobalVariables.BassHandle, 0);
    TimeLabel.Text = FormatTime(Imports.BASS_ChannelBytes2Seconds(GlobalVariables.BassHandle, (uint)current)) + "/" + FormatTime(Imports.BASS_ChannelBytes2Seconds(GlobalVariables.BassHandle, (uint)GlobalVariables.PlayBackLength));
}

【解决方案1】：

您可以使用progressBar1.Margin.Left - 代表X，progressBar1.Margin.Top - 代表Y。但是相对于放置 ProgressBar 的 Container 会有价值。

【讨论】：

我希望它们相对于 ProgressBar 的放置位置。谢谢。
