C#winform動態(tài)高頻刷新顯示圖片實例-winform多圖片刷新顯示

有時候需要高頻刷新圖片，為了提高性能使用MemoryStreamMemoryStream創(chuàng)建一個流，其后備存儲為\h內存MemoryStream類用于向內存而不是磁盤讀寫數據。MemoryStream封裝以無符號字節(jié)\h數組形式存儲的數據，該數組在創(chuàng)建MemoryStream可創(chuàng)建為空數組。可在內存中直接訪問這些封裝的數據。內存流可降低應用程序中對臨時緩沖區(qū)和臨時文件的需要。高速定時讀取本地圖片并在另外定時器中刷新到窗體控件PictureBox中。定時器計時設置為1msusingusingusingusingnamespacepublicpartialclassForm1:MemoryStreamms;//public/////////publicstaticclassconstintBufferSize=publicstaticvoidCopyTo(Streaminput,Streambyte[]buffer=newintwhile((read=input.Read(buffer,0,buffer.Length))>output.Write(buffer,0,publicstaticbyte[]ReadFully(Streamusing(MemoryStreamtempStream=newCopyTo(input,return//////publicstaticclasspublicstaticbyte[]ReadFully(Streambyte[]bytes=newfileStream.Read(bytes,0,return//privatevoidbutton1_Click(objectsender,EventArgstimer1.Enabled=timer2.Enabled=privatevoidtimer1_Tick(objectsender,EventArgsBitmapbmpt=new
