dll:

一、Models
1.StaffModel.cs

using GalaSoft.MvvmLight;
using System;
using System.Collections.Generic;
using System.Text;

namespace WpfApp33.Models
{
    public class StaffModel : ObservableObject
    {
        private string id;
        /// <summary>
        /// 身份证
        /// </summary>
        public string ID
        {
            get { return id; }
            set { id = value; RaisePropertyChanged(() => ID); }
        }

        private string name;
        /// <summary>
        /// 姓名
        /// </summary>
        public string Name
        {
            get { return name; }
            set { name = value; RaisePropertyChanged(() => Name); }
        }
    }
}

二、ViewModels
1.StaffViewModel.cs

using GalaSoft.MvvmLight;
using System;
using System.Collections.Generic;
using System.Text;
using WpfApp33.Models;

namespace WpfApp33.ViewModels
{
    public class StaffViewModel : ViewModelBase
    {
        public StaffViewModel()
        {
            Staff = new StaffModel() { ID = "xxx22119990815xxxx", Name = "张xx" };
        }

        #region 属性
        private StaffModel staff;
        /// <summary>
        /// 职员属性
        /// </summary>
        public StaffModel Staff
        {
            get { return staff; }
            set { staff = value; RaisePropertyChanged(() => Staff); }
        }

        #endregion
    }
}

2.ViewModelLocator.cs

/*
  In App.xaml:
  <Application.Resources>
      <vm:ViewModelLocator xmlns:vm="clr-namespace:MVVMLightDemo"
                           x:Key="Locator" />
  </Application.Resources>

  In the View:
  DataContext="{Binding Source={StaticResource Locator}, Path=ViewModelName}"

  You can also use Blend to do all this with the tool's support.
  See http://www.galasoft.ch/mvvm
*/

using GalaSoft.MvvmLight;
using GalaSoft.MvvmLight.Ioc;
using WpfApp33.ViewModels;

namespace WpfApp33.ViewModels
{
    /// <summary>
    /// This class contains static references to all the view models in the
    /// application and provides an entry point for the bindings.
    /// </summary>
    public class ViewModelLocator
    {
        /// <summary>
        /// Initializes a new instance of the ViewModelLocator class.
        /// </summary>
        public ViewModelLocator()
        {

            #region Code Example
            if (ViewModelBase.IsInDesignModeStatic)
            {
                // Create design time view services and models
                SimpleIoc.Default.Register<IDataService, DesignDataService>();
            }
            else
            {
                // Create run time view services and models
                SimpleIoc.Default.Register<IDataService, DataService>();
            }
            #endregion

            //SimpleIoc.Default.Register<MainViewModel>();
            SimpleIoc.Default.Register<StaffViewModel>();
        }

        #region 实例化
        //public MainViewModel Main
        //{
        //    get
        //    {
        //         return SimpleIoc.Default.GetInstance<MainViewModel>();
        //    }
        //}

        public StaffViewModel Staff
        {
            get
            {
                return SimpleIoc.Default.GetInstance<StaffViewModel>();
            }
        }

        #endregion

        public static void Cleanup()
        {
            // TODO Clear the ViewModels
        }
    }
}

三、View
1.StaffView.xaml

<Window x:Class="WpfApp33.Views.StaffView"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        mc:Ignorable="d"
        DataContext="{Binding Source={StaticResource Locator},Path=Staff}"
        Title="StaffView" Height="450" Width="800"  >
    
    <Grid>
        <StackPanel>
            <TextBlock Text="{Binding Staff.ID}" Height="30" Width="200" Background="LightBlue"/>
            <TextBlock Text="{Binding Staff.Name}" Height="30" Width="200" Background="LightCoral"/>     
        </StackPanel>
    </Grid>
</Window>

四、解决方法资源管理器

值得注意的是：
1.App.xaml 中需要将ViewModelLocator添加为应用程序资源"Locator"，否则StaffView.xaml中无法直接静态引用。
2.App.xaml中需要设置StartupUri为Views/StaffView.xaml，否则看不到StaffView.xaml。

<Application x:Class="WpfApp33.App"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:local="clr-namespace:WpfApp33" 
        xmlns:vm="clr-namespace:WpfApp33.ViewModels"
        StartupUri="Views/StaffView.xaml">
    <Application.Resources>
        <vm:ViewModelLocator x:Key="Locator" />
    </Application.Resources>
</Application>
