**********===普通方案***************====
private void button1_click(object sender, eventargs e)
this.label1.text = "複製完成，共手複製檔案" + files.length.tostring() + "個";
} 你的邏輯類
public class fileoperator }
**********下面是多執行緒的方案***************==
private void button1_click(object sender, eventargs e)
); }
private void startcopy(object path)
));
foreach(fileinfo file in files )
));
//this.label1.refresh();
fileoperator.copyfile(file.fullname, dir2.fullname + "//" + file.name);
this.progressbar1.invoke(new methodinvoker(delegate ));
} this.label1.invoke(new methodinvoker(delegate ));
} }
public class fileoperator }
********************====下面是非同步方案********************==
定義乙個委託
delegate void copyhandler(string file1, string file1);
呼叫委託的begininvoke和endinvoke
具體**如下：
private void button1_click(object sender, eventargs e)
); }
//非同步委託物件
delegate void copyhandler(string file1, string file2);
private void startcopy(object path)
));
copyhandler copyhandler = new copyhandler(fileoperator.copyfile);
foreach (fileinfo file in files) }
private void asynccallback(iasyncresult result)
));
asyncresult r = (asyncresult)result;
copyhandler handler = (copyhandler)r.asyncdelegate;
handler.endinvoke(result);
this.progressbar1.invoke(new methodinvoker(delegate ));
} }
public class fileoperator }
