Question

C#可以读取盘符，要怎么样才可以显示盘名？

DriveInfo[] dr = DriveInfo.GetDrives();
foreach (DriveInfo dd in dr)
{
if (dd.DriveType == DriveType.CDRom) //过滤掉是光驱的 磁盘
{
return;
}
else
{
dataGridView1.Rows.Add(dd);
dataGridView1.AllowUserToAddRows = false;
}
}
DriveInfo[] drives = Directory.GetLogicalDrives().Select(q => new DriveInfo(q)).ToArray();
foreach (var driveInfo in drives)
{
if (driveInfo.IsReady)
{
dataGridView1.Rows.Add(driveInfo.VolumeLabel);
}
}
这一个是读取盘名的，两个要怎么整合？有没有哪位大神知道？

Answer 1

DriveInfo[] allDrives = DriveInfo.GetDrives();

foreach (DriveInfo d in allDrives)
{
Console.WriteLine("Drive {0}", d.Name);
Console.WriteLine(" File type: {0}", d.DriveType);
if (d.IsReady == true)
{
Console.WriteLine(" Volume label: {0}", d.VolumeLabel);
Console.WriteLine(" File system: {0}", d.DriveFormat);
Console.WriteLine(
" Available space to current user:{0, 15} bytes",
d.AvailableFreeSpace);

Console.WriteLine(
" Total available space: {0, 15} bytes",
d.TotalFreeSpace);

Console.WriteLine(
" Total size of drive: {0, 15} bytes ",
d.TotalSize);
}
}

用不了，我是要显示到dataGridView1的，不知道是不是我修改错了

追答

DataTable dt = New DataTable()
dt.Columns.Add(New DataColumn("dName", GetType(String)))

foreach (var driveInfo in drives)
{
if (driveInfo.IsReady)
{
var dr = dt.NewRow();
dr[0]=driveInfo.VolumeLabel;
dt.Rows.Add(dr);

}
}
dataGridView1.datasource=dt;
--winform 不用下面一行，WEB需要下一行代码
dataGridView1.DataBind();

追问

还是不行，会出现这种错误

追答

new 小写 n
DataSource
这种是基本，你自己一点都不会改吗
这里手工打，不可能和代码编辑器里一样的，有时大小写这种属性问题要自己解决。
