WPF+MVVM的问题<br />

我现在有点小疑惑了，恩，就是跨类添加数据的时候出现了一个小问题。

首先是父类的代码。

 //实现功能的方法  

        public void addCompanyCommand()

        {

            AddCompanyInfo add = new AddCompanyInfo();

            add.addDataEvent += new AddDataDelegate(addevenData);

            add.ShowDialog();

  //AddCompanyInfoViewModel addcompany = new AddCompanyInfoViewModel();

            //addcompany.addDataEvent += new addDataDelegate(addevenData);

            //addcompany.ShowView();

            //addcompany.addData += new AddCompanyInfoViewModel.AddData(addevenData);

            //add.ShowDialog();

            //IBaseViewModel view = new AddCompanyInfo();

            //view.Show();

}

 子类的方法

namespace OptWpfApp

{

    public delegate void addDataDelegate(CompanyInfoModel model);

    public class AddCompanyInfoViewModel : BaseViewModel, INotifyPropertyChanged

    {

         public event addDataDelegate addDataEvent;

        public AddCompanyInfoViewModel()

        {

            _addCompanyCommand = new RelayCommand(addCompanyCommand) { IsEnabled = true };

        }

        //public void ShowView()

        //{

        //    AddCompanyInfo add = new AddCompanyInfo();

        //    add.ShowDialog();

        //}

        public void showViewEvent()

        {

        }

        //实现功能的方法  

        public void addCompanyCommand()

        {

            CompanyInfoModel model = new CompanyInfoModel()

            {

                CompanyNo = CompanyNo,

                CompanyName = CompanyName,

                RegisteredAddress = RegisteredAddress,

                OfficeAddress = OfficeAddress,

                CorporateRepresentative = CorporateRepresentative,

                RegisteredCapital = RegisteredCapital,

                ScopeBusiness = ScopeBusiness,

                Code = Code,

                CompanyCreateTime = CompanyCreateTime,

                YingYeStartTime = YingYeStartTime,

                YingYeEndTime = YingYeEndTime

            };

            //if (addDataEvent != null)

            //{

            //    addDataEvent(model);

            //}

            // addData += new AddData(model);

            //if (addData != null)

            //{

            //    addData(model);

            //}
