ViewModels下创建 MainViewModel  

using Prism.Commands;
using Prism.Mvvm;
using WPF01.Views;

namespace WPF01.ViewModels
{
    public class MainViewModel : BindableBase
    {
        /// <summary>
        /// 定义带参代理给前端调用
        /// </summary>
        public DelegateCommand<string> OpenCommand { get; private set; }
        public MainViewModel()
        {
            OpenCommand = new DelegateCommand<string>(Open);
        }

        private object body;
        public object Body { get { return body; } set { body = value; RaisePropertyChanged(); } }

        private void Open(string obj)
        {
            switch (obj)
            {
                case "ViewA": Body = new ViewA(); break;
                case "ViewB": Body = new ViewB(); break;
                case "ViewC": Body = new ViewC(); break;
            }
        }
    }
}
