private void button8_Click(object sender, EventArgs e)
{
List<long> averages;
long res = 0;
_fi = new DirectoryInfo(subDirectoryName).GetFiles("*.bmp");
averages = new List<long>(_fi.Length);
for (int i = 0; i < _fi.Length; i++)
{
Bitmap myBitmaps = new Bitmap(_fi[i].Name);
//long[] tt = list_of_histograms[i];
long[] HistogramValues = GetHistogram(myBitmaps);
res = GetTopLumAmount(HistogramValues,1000);
averages.Add(res);
}
}
例外是在线:
Bitmap myBitmaps = new Bitmap(_fi[i].Name);

您只是将文件名传递给Bitmap
构造函数,但实际上应该使用_fi[i].FullName

@Lester是正确的答案(+1),但我确实想说你可以缩短你的实现,并通过使用一些函数式编程结构使它更具可读性:
var averages = new DirectoryInfo(subDirectoryName)
.GetFiles("*.bmp")
.Select(t => new Bitmap(t.FullName))
.Select(GetHistogram)
.Select(v => GetTopLumAmount(v, 1000))
.ToList();

你试过.FullName
吗?这应该包括整个目录。
