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;
