截断!!!! SetDesktopUrl明显有问题
网上有一个解决办法 是查询 syslistview32 里面item的位置
public bool SetDesktopUrl(string lnkname,string filepath) { try { ShellLink link = new ShellLink(); ((IPersistFile)link).Load(lnkname, STGM_READ); ((IShellLinkW)link).SetPath(filepath); ((IPersistFile)link).Save(lnkname, true); return true; } catch { return false; } }

.net可以引和一个脚本的com来创建。
具体的问google.
