不过可以先帖上权限的核心控制部分的代码:

/// <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 { } 
        } 
    } 
}
