バイナリファイルを読んでいます。1 つのファイルを読み取ると、コードは正常に動作します。しかし、フォルダー内のファイルを読み取ると、エラーが発生し、以下に貼り付けられます。ファイルの読み取りに使用しているコードをいくつか追加します。私はバイト配列でファイルを読んでいます:

byte[] b = File.ReadAllBytes(args);

データを配列に格納する (指標コード):

len=400000000;
public ArrayList rawData1 = new ArrayList();
UInt32[] fff = Enumerable.Repeat((UInt32)4095, len/4).ToArray();    


public ReadRawFiles{
            while (true){
            rawData1.Add((double)(BitConverter.ToUInt32(b, curPos) & fff[i]));
            i++;
            }
}
b=null; //clear array

ファイルを 1 つだけ読み込むと、速度は遅くなりますが (サイズは約 40 MB)、動作します。しかし、フォルダーのパスを追加して再度読み取ると、エラーが発生します。

List<ReadRawFiles> list = new List<ReadRawFiles>();
ReadRawFiles rawFiles;
foreach (var f in sFiles)
                    {
                      rawFiles = new ReadRawFiles(f.File,true,true);
                      list.Add(rawFiles);

                       //rawFiles=null; //clear??
                    }

ガベージコレクターの仕組みがよくわかりません。何か見逃した場合はお知らせください。

よろしくお願いします。

私はそれがこれによるものだと思います：

while (true)
{
    rawData1.Add((double)(BitConverter.ToUInt32(b, curPos) & fff[i]));
    i++;
}

終了条件はありません。それは永遠に続き、データをインクリメントしてArrayListiに追加することでリソースを消費し続けます。rawData
