对象引用时的错误未设置为对象的实例。 [英] Error at object reference not set to an instance of an object.

问题描述

objModel模型为null&

objModel Model is null &

public ClusterModel()

不是tri€


我尝试过：



查看页面：



@model COCSIntimation.Models.ISIProcessListModel



@ {Html.RenderPartial（_ Cluster，Model.objModel）;在对象引用未设置为对象实例时获取错误。



型号：



公共类ISIProcessListModel

{

public ClusterDetails.ClusterModel objModel {get;组; }

}



控制器：



public ActionResult Index（）

{

ISIProcessListModel objProcessModel = new ISIProcessListModel（）;

返回View（objProcessModel）;

}



类库：



公共类ClusterModel

{

public ObservableCollection< SelectListItem>参数;

公共字符串MCLELDescription {get;组; } $ / $


public ClusterModel（）

{

string companycode = HttpContext.Current.Session [iCompanyCode ] .ToString（）;

int icompanycode = Convert.ToInt32（companycode）;



string CECodes =2,3,4， 5,6,7;

SharedDA.GeneralClass obj = new SharedDA.GeneralClass（）;

DataSet objds = new DataSet（）;

objds =（DataSet）obj.GetClusterElements（1，CECodes）;

var empList = objds.Tables [0] .AsEnumerable（）。选择（dataRow => new ClusterModel {MCLELDescription = dataRow。字段< string>（MCLEL_Description）}）。ToList（）;



}

}





部分查看：



@model ClusterDetails.ClusterModel





@（Html.EIPMVCLabel（lblIndependentCompany，@ Model.MCLELDescription））

is not trigerring

What I have tried:

View Page:

@model COCSIntimation.Models.ISIProcessListModel

@{ Html.RenderPartial("_Cluster", Model.objModel); } Getting error at "Object reference not set to an instance of an object."

Model:

public class ISIProcessListModel
{
public ClusterDetails.ClusterModel objModel { get; set; }
}

Controller:

public ActionResult Index()
{
ISIProcessListModel objProcessModel = new ISIProcessListModel();
return View(objProcessModel);
}

Class Library:

public class ClusterModel
{
public ObservableCollection<SelectListItem> Parameters;
public string MCLELDescription { get; set; }

public ClusterModel()
{
string companycode = HttpContext.Current.Session["iCompanyCode"].ToString();
int icompanycode = Convert.ToInt32(companycode);

string CECodes = "2,3,4,5,6,7";
SharedDA.GeneralClass obj = new SharedDA.GeneralClass();
DataSet objds = new DataSet();
objds = (DataSet)obj.GetClusterElements(1, CECodes);
var empList = objds.Tables[0].AsEnumerable().Select(dataRow => new ClusterModel { MCLELDescription = dataRow.Field<string>("MCLEL_Description") }).ToList();

}
}


Partial View:

@model ClusterDetails.ClusterModel


@(Html.EIPMVCLabel("lblIndependentCompany", @Model.MCLELDescription))

推荐答案

尝试如下：

Try like below:

@{Html.RenderPartial("_Cluster", new ViewDataDictionary(Model.MCLELDescription))};

尝试如下：

Try like below:

@{Html.RenderPartial("", new ViewDataDictionary(Model.MCLELDescription))};
