c# - 在 C# Windows 应用程序中使用 Progressbar

Question

用户将能够在本地机器上搜索一些文档，我想在我的程序搜索过程中向用户显示一个进度条。更清楚地说，我有 foreach 循环，我想为其绑定(bind)进度条以显示进度。我的 foreach 循环和进度应该同时工作。这可能吗？

来自 ProgressBar Class

你可以尝试类似的东西

private void CopyWithProgress(string[] filenames)
{
    // Display the ProgressBar control.
    pBar1.Visible = true;
    // Set Minimum to 1 to represent the first file being copied.
    pBar1.Minimum = 1;
    // Set Maximum to the total number of files to copy.
    pBar1.Maximum = filenames.Length;
    // Set the initial value of the ProgressBar.
    pBar1.Value = 1;
    // Set the Step property to a value of 1 to represent each file being copied.
    pBar1.Step = 1;

    // Loop through all files to copy.
    for (int x = 1; x <= filenames.Length; x++)
    {
        // Copy the file and increment the ProgressBar if successful.
        if(CopyFile(filenames[x-1]) == true)
        {
            // Perform the increment on the ProgressBar.
            pBar1.PerformStep();
        }
    }
}
