基于.NET CORE 8.0使用C#写一个winform的视频分割工具，需要可以选择输入文件，输出路径，输出格式，分割方式时长（秒）或文件大小（MB），有进度条可以看到当前执行状态。自定义输出文件名称，格式为：文件名_数字顺序。需要分别给我完整的Form1.cs文件和Form1.Designer.cs文件的代码
好的，下面是一个基于.NET Core 8.0的WinForms应用程序的示例代码，用于实现视频分割工具。这个工具允许用户选择输入文件、输出路径、输出格式，并根据时长（秒）或文件大小（MB）进行分割。它还包括一个进度条来显示当前执行状态，并支持自定义输出文件名称格式。

{
using (OpenFileDialog openFileDialog = new OpenFileDialog())
{
openFileDialog.Filter = "Video Files|*.mp4;*.avi;*.mkv;*.mov";
if (openFileDialog.ShowDialog() == DialogResult.OK)
{
txtInputFile.Text = openFileDialog.FileName;
}
}
}
private void btnBrowseOutput_Click(object sender, EventArgs e)
{
using (FolderBrowserDialog folderBrowserDialog = new FolderBrowserDialog())
{
if (folderBrowserDialog.ShowDialog() == DialogResult.OK)
{
txtOutputPath.Text = folderBrowserDialog.SelectedPath;
}
}
}
private void btnStart_Click(object sender, EventArgs e)
{
string inputFile = txtInputFile.Text;
string outputPath = txtOutputPath.Text;
string outputFormat = cmbOutputFormat.SelectedItem.ToString();
string splitOption = cmbSplitOption.SelectedItem.ToString();
int splitValue = int.Parse(txtSplitValue.Text);
string outputFileName = txtOutputFileName.Text;
if (string.IsNullOrEmpty(inputFile) || string.IsNullOrEmpty(outputPath) || string.IsNullOrEmpty(outputFileName))
{
MessageBox.Show("Please fill in all fields.");
return;
}
progressBar.Value = 0;
progressBar.Maximum = 100;
// Here you would call your video splitting logic
// For demonstration, we will use a dummy loop to simulate progress
for (int i = 0; i <= 100; i++)
{
progressBar.Value = i;
System.Threading.Thread.Sleep(50); // Simulate work

请注意，这个示例代码���，视频分割的实际逻辑部分（如调用FFmpeg等工具进行视频分割）并未实现。你需要根据具体需求和使用的工具来实现视频分割的逻辑。
