如何将DataContracts列表转换为整数数组[] [英] How to convert a List of DataContracts to an to an Integer array[]

问题描述

大家好，



我需要将数据合同列表转换为整数数组[]

从C＃转换为整数在C ++ / CLI中使用array []然后再使用C ++。



能不能让我知道如何实现这个目标。



感谢你的帮助。

  //   topicDetails是数据合同 
 CreateSubscriptions< List< TopicDetails>（topicDetails）; 
 
  //  这里的TopicDetails是一个类（数据合约），如下所示。 
 
  public   class  TopicDetails 
 {
  protected   object  baseObjectType;  //   string  
  protected  对象主题;  //   string  
 
  public  TopicDetails（）; 
 
 [DataMember] 
  public   object  BaseObjectType {获得;  set ; } 
 [DataMember] 
  public   object  TopicID {获得;  set ; } 
 
  public   static  TopicDetails CreateTopic< T，mT>（IComparable< T> ; objectType，IComparable< mT> objectID）; 
} 

解决方案

大家好，



以下代码正在努力满足要求。

请看一下。

将Datacontracts列表转换为整数数组。



< pre lang =c＃> int [] data;

var obj = topicDetails; // topicDetails =新列表< TopicDetails> {}; // DataContracts列表{BaseObjectType =：EQUIPMENT，TopicID =42};
var serializer = new System.Runtime.Serialization.DataContractSerializer（ typeof （List< TopicDetails>））;

使用（ var stream = new System.IO.MemoryStream（））
{
serializer.WriteObject（stream，obj）;

data = new int [stream.Length];
stream.Position = 0 ;

for （ int i = 0 ; i < data.Length; i ++）
data [i] = stream.ReadByte（）;
}

Hi All ,

I need to convert a List of data contracts to an integer array[]
from C# to an Integer array[] in C++/CLI and then to C++.

Could you please let me know how can I achive this.

Appreciate your help on this.

//topicDetails is a data-contract
CreateSubscriptions<List<TopicDetails>(topicDetails);

//Here TopicDetails is a class (data contract) as follows.

public class TopicDetails
{
        protected object baseObjectType;  //string
        protected object topic;            //string

        public TopicDetails();

        [DataMember]
        public object BaseObjectType { get; set; }
        [DataMember]
        public object TopicID { get; set; }

        public static TopicDetails CreateTopic<T, mT>(IComparable<T> objectType, IComparable<mT> objectID);
}

解决方案

Hi All,

The following code is working to satisfy the requirement.
Please take a look at it.
To convert List of Datacontracts to an integer array.

 int[] data;

var obj = topicDetails;// topicDetails= new List<TopicDetails> { };// List of DataContracts{ BaseObjectType = ":EQUIPMENT", TopicID = "42" };
           var serializer = new System.Runtime.Serialization.DataContractSerializer(typeof(List<TopicDetails>));

           using (var stream = new System.IO.MemoryStream())
           {
               serializer.WriteObject(stream, obj);

               data = new int[stream.Length];
               stream.Position = 0;

               for (int i = 0; i < data.Length; i++)
                   data[i] = stream.ReadByte();
           }
