c# net 使用反射为对象赋值

 public T Bson2T(MongoDB.Bson.BsonDocument bson)
         {
             T t = default(T);

             //获取T类中的所有属性
             PropertyInfo[] TpropertyInfo = typeof(T).GetProperties(System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.Public | System.Reflection.BindingFlags.NonPublic);

             //用反射自动创建泛型对象
             t=System.Activator.CreateInstance<T>();

             foreach (PropertyInfo pInfo in TpropertyInfo)
             {
                 string pInfo_name=pInfo.Name;

                 //PropertyInfo bsonPropertyInfo= bson.GetType().GetProperty(pInfo_name);

                 //object bsonValue=bsonPropertyInfo.GetValue(bson,null);

                 object bsonValue = BsonGetValue(bson.ToString(), pInfo_name);

                 //给属性赋值
                 pInfo.SetValue((object)t,bsonValue,null);
             }
             return t;
