使用此处描述的解决方案,我编写了以下方法:
const string ShellIdListArrayName = "Shell IDList Array";
static IEnumerable<string> GetPathsFromShellIDListArray(IDataObject data)
{
if (data.GetDataPresent(ShellIdListArrayName))
{
var ms = (MemoryStream)data.GetData(ShellIdListArrayName);
byte[] bytes = ms.ToArray();
IntPtr p = Marshal.AllocHGlobal(bytes.Length);
Marshal.Copy(bytes, 0, p, bytes.Length);
uint cidl = (uint)Marshal.ReadInt32(p, 0);
int offset = sizeof(uint);
IntPtr parentpidl = (IntPtr)((int)p + (uint)Marshal.ReadInt32(p, offset));
StringBuilder path = new StringBuilder(256);
SHGetPathFromIDList(parentpidl, path);
for (int i = 1; i <= cidl; ++i)
{
offset += sizeof(uint);
IntPtr relpidl = (IntPtr)((int)p + (uint)Marshal.ReadInt32(p, offset));
IntPtr abspidl = ILCombine(parentpidl, relpidl);
if (SHGetPathFromIDList(abspidl, path) != 0)
{
yield return path.ToString();
}
ILFree(abspidl);
}
}
}
[DllImport("shell32.dll")]
public static extern int SHGetPathFromIDList(IntPtr pidl, StringBuilder pszPath);
[DllImport("shell32.dll")]
public static extern IntPtr ILCombine(IntPtr pidl1, IntPtr pidl2);
[DllImport("shell32.dll")]
public static extern void ILFree(IntPtr pidl);
您可以将 e.Data 从您的事件处理程序传递给此方法,您将获得一系列路径(假设这些项目当然有路径......例如,“我的电脑”没有路径)
