c# - TIF 文件中 C# 中的 OutofMemory 错误

Question

当扫描超过 1366 个文件时会报错 代码计算所选文件夹中的 tif 文件 代码:

 int mergeTiffPages(string[] path)
    {
        Cursor.Current = Cursors.WaitCursor;
        string[] sa = path;
        int frame = 0;
        Bitmap bitmap;
        int count = 0 ;
        foreach (string s in sa)
        {
            {
                try
                {
                    bitmap = (Bitmap)Image.FromFile(s);//Its will raise an error OutOf Memory
                    if (bitmap != null)
                    {
                        count = bitmap.GetFrameCount(FrameDimension.Page);
                        frame += count;
                        bitmap = null;
                        count = 0;
                    }
                }
                catch(Exception ex)
                {
                    MessageBox.Show("Not TIFF image file. please select the folder in which tif file is available", "Warning", MessageBoxButtons.OK, MessageBoxIcon.Error);
                }
            }
        }

        cntval.Text = frame.ToString();
        Cursor.Current = Cursors.Default;
        return 1;

    }

在path函数中设置所有图片文件的数组

Error:OutOfMemory

使用这个:

 using (bitmap = (Bitmap)Image.FromFile(s))
                        {

                               ...                          
                        }
