我想我是使用非托管方法获得的。结果在 C# 中有点难看，但概念如下：
uint nOSErr;
if(!(nOSErr = setFolderPermissions(@"C:\inetpub\www_test1", @"IIS AppPool\" + strAppPoolName, OSFileAccess.FILE_GENERIC_READ)))
{
throw new Exception("Failed to change permissions, error code=" + nOSErr);
}
public static uint setFolderPermissions(string strFolderPath, string strUserName, OSFileAccess access)
{
//Set folder permissions
//RETURN:
// = 0 if success
// = Otherwise error code -- check GetLastError
uint dwRes = 0;
try
{
IntPtr pZero = IntPtr.Zero;
IntPtr pSecDesc = pZero;
IntPtr pDacl = pZero;
if ((dwRes = GetNamedSecurityInfo(strFolderPath, SE_OBJECT_TYPE.SE_FILE_OBJECT, SECURITY_INFORMATION.DACL_SECURITY_INFORMATION,
out pZero, out pZero, out pDacl, out pZero, out pSecDesc)) == ERROR_SUCCESS)
{
try
{
EXPLICIT_ACCESS ea = new EXPLICIT_ACCESS();
ea.grfAccessPermissions = access;
ea.grfAccessMode = AccessMode.GRANT_ACCESS;
ea.grfInheritance = AceFlags.CONTAINER_INHERIT_ACE | AceFlags.OBJECT_INHERIT_ACE;
ea.Trustee.MultipleTrusteeOperation = UIntPtr.Zero;
ea.Trustee.pMultipleTrustee = UIntPtr.Zero;
ea.Trustee.TrusteeForm = (UIntPtr)(TrusteeForm.TRUSTEE_IS_NAME);
ea.Trustee.ptstrName = strUserName;
IntPtr pNewDacl = pZero;
if((dwRes = SetEntriesInAcl(1, ref ea, pDacl, out pNewDacl)) == ERROR_SUCCESS)
{
try
{
if ((dwRes = SetNamedSecurityInfo(strFolderPath, SE_OBJECT_TYPE.SE_FILE_OBJECT, SECURITY_INFORMATION.DACL_SECURITY_INFORMATION,
IntPtr.Zero, IntPtr.Zero, pNewDacl, IntPtr.Zero)) == ERROR_SUCCESS)
{
//Done
}
}
finally

//Free mem
if (pNewDacl != IntPtr.Zero)

pNewDacl = IntPtr.Zero;

}
}
}
