check user permissions for specific file in sharepoint client object model

Question

I want to check if specific user has which permission for specific file or folder of any document library in share point client object model.

Answer 1

SPlistitem has a function DoesuserhavePermission, http://msdn.microsoft.com/en-us/library/ms472022.aspx

try this one,

SPList objList = web.GetList(this.NewsItemURL);
SPListItem objListItem = null;

try
{
     objListItem = objList.GetItemById(_intNewsItemID);
 if (!objListItem.DoesUserHavePermissions(web.CurrentUser, SPBasePermissions.ViewListItems))
 {
     _strErrMsg = "Does not have permission";
 }

}

catch (ArgumentException)
{
     objListItem = null;
}
