反射控制权限 精细版

 
不过可以先帖上权限的核心控制部分的代码:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23

/// <summary> /// 设置form上的组件的权限 /// </summary> /// <param name="form">控件所在的窗体</param> /// <param name="getPermissionsHandler">取得form里组件名及其Enabled属性(当前用户)的键值对</param> public static void SetPermissions(this Form form, Func<Form, IDictionary<string, bool>> getPermissionsHandler) {     Type t = form.GetType();     FieldInfo[] fs = t.GetFields(BindingFlags.NonPublic | BindingFlags.Public | BindingFlags.Instance | BindingFlags.Static);     IDictionary<string, bool> permissions = getPermissionsHandler(form);     foreach (FieldInfo f in fs)     {         dynamic component = f.GetValue(form);         if (component is System.ComponentModel.Component && permissions.ContainsKey(f.Name))         {             try             {                 component.Enabled = permissions[f.Name];             }             catch { }         }     } }

getPermissionsHandler可以使权限的获取方式与权限赋值分离, 以得到多种权限组合. Lambda, Linq, 结合一个表达是就可以搞定.
