C#winform動(dòng)態(tài)高頻刷新顯示圖片實(shí)例-winform多圖片刷新顯示

有時(shí)候需要高頻刷新圖片，為了提高性能使用MemoryStreamMemoryStream創(chuàng)建一個(gè)流，其后備存儲(chǔ)為\h內(nèi)存MemoryStream類用于向內(nèi)存而不是磁盤讀寫數(shù)據(jù)。MemoryStream封裝以無符號(hào)字節(jié)\h數(shù)組形式存儲(chǔ)的數(shù)據(jù)，該數(shù)組在創(chuàng)建MemoryStream可創(chuàng)建為空數(shù)組?？稍趦?nèi)存中直接訪問這些封裝的數(shù)據(jù)。內(nèi)存流可降低應(yīng)用程序中對臨時(shí)緩沖區(qū)和臨時(shí)文件的需要。高速定時(shí)讀取本地圖片并在另外定時(shí)器中刷新到窗體控件PictureBox中。定時(shí)器計(jì)時(shí)設(shè)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
