或者可能是......

    fiContents.Append(fi.ReadToEnd());

现在让我们去超级赛亚人片刻做一些真正有趣的东西,比如有一个BackgroundWorker可以让我们显示一个加载图像(我将使用它),提供一个进程倒数计时器或ProgressBar.

public void ReadFile(string filename)
{
    BackgroundWorker procFile = new BackgroundWorker();
    // Progress 1: If we want to show the progress we need to enable the following property
    // procFile.WorkerReportsProgress = true;

    profile.DoWork += new DoWorkEventHandler((object obj, DoWorkEventArgs ev) =>
    {
        StringBuilder fiContents = new StringBuilder();
