【反射】获取Web项目中的Controller和Action

前言

在使用时需要修改命名空间、需要过滤控制器、需要过滤Action方法。
结果生成表的插入语句。

代码

public ActionResult ReloadData()
{
    #region 获取所有的控制器类
    System.Text.StringBuilder sbSql = new System.Text.StringBuilder();
    List<Type> controllerTypes = new List<Type>();    //创建控制器类型列表
    var assembly = System.Reflection.Assembly.Load("Qshds.Controllers.Manage");    //加载程序集
    controllerTypes.AddRange(assembly.GetTypes().Where(type => typeof(IController).IsAssignableFrom(type) && type.Name != "ErrorController"));    //获取程序集下所有的类，通过Linq筛选继承IController类的所有类型                        
    foreach (var controller in controllerTypes)//遍历控制器类
    {
        var actions = controller.GetMethods().Where(method => method.ReturnType.Name == "ActionResult");    //获取控制器下所有返回类型为ActionResult的方法，对MVC的权限控制只要限制所以的前后台交互请求就行，统一为ActionResult
        foreach (var action in actions)
        {
            var catt = action.CustomAttributes.Where(x => x.AttributeType.Name == "FunctionFilter").ToList();
            if (catt.Count > 0)
            {
                var s1 = catt[0].NamedArguments[0].TypedValue;
                var s2 = catt[0].NamedArguments[1].TypedValue;
                var s3 = string.Format("/{0}/{1}/", controller.Name.Replace("Controller", ""), action.Name);
                sbSql.AppendFormat("INSERT INTO A_GetAllAction(NAME,Code,Url,Sort,ActionType,[CHECK],InsertTime) VALUES('{0}','{1}','{2}',0,0,1,getdate())"
                    , s2.ToString().Replace("\"您当前没有", "").Replace("的权限！\"", "")
                    , s1.ToString().Replace("\"", ""), s3);
            }
        }
    }
    var res = sbSql.ToString();
    #endregion
    return new RedirectResult("/Action/" + Request.Url.Query);
}
