OpenFileDialog ofg = new OpenFileDialog();
ofg.Title = "ddd";//设置对话框标题
ofg.Multiselect = true;//设置对话框可以多选
ofg.InitialDirectory = ;//设置对话框的初始目录
ofg.Filter = //设置文件类型
ofg.ShowDialog();
string path = ofg.FileName;
if(path == "")
{
return;
}
using(FileStream isread = new FileStream(path,FileMode.OpenOrCreate,FileAccess.Read))
{
byte[] buffer = new byte[1024*1024*5];
//设置读取到的字节数
int r = isread.Read(buffer,0,buffer.Length);
textbox1.text = Encoding.Default.GetString(buffer,0,r);
}
小知识点： combobox.Items.clear() 命名：cbo.... selectedindexchanged combobox.selectitem.tostring() comboBox1.SelectedItem.ToString().Split(new char[] { ‘月‘ }, StringSplitOptions.RemoveEmptyEntries); listbox：直接项或者代码加项 listbox.selectedindex listbox_doubleclick path.GetFileName 双击播放音乐： SoundPlayer sp = new SoundPlayer(); sp.SoundLocation = ... sp.Play();
