C# 中怎么获得 NEWSEQUENTIALID() 值

C# 中如何获得 NEWSEQUENTIALID() 值
获取newid值可以用Guid.NewGuid（）方法，获取NEWSEQUENTIALID()值该怎么办呢
我环境是VS2008+sql2008

[解决办法]
可以参考代码

另外
NEWSEQUENTIALID 是对 Windows UuidCreateSequential 函数的包装。你还可以这样
protected void btn_Click(object sender, EventArgs e)
{
Guid dd;
UuidCreateSequential(out dd);
Console.Write(dd.ToString());
}

[System.Runtime.InteropServices.DllImport("rpcrt4.dll", SetLastError = true)]
static extern int UuidCreateSequential(out Guid guid);
