c# - C# .net 2.0 中从帖子到字典或哈希表的字符串 []

Question

我有一个帖子，其中包含一组项目，其中没有键的 int 而是键的字符串。例如：（来自帖子）

-----------------------------3805226668837
Content-Disposition: form-data; name="pool[Abelson_2834.jpg]"

general_pool
-----------------------------3805226668837
Content-Disposition: form-data; name="pool_place[Abelson_2834.jpg]"

1
-----------------------------3805226668837
Content-Disposition: form-data; name="mediatype[Abelson_2834.jpg]"

3
-----------------------------3805226668837
Content-Disposition: form-data; name="pool[Abelson_2852.jpg]"

general_pool
-----------------------------3805226668837
Content-Disposition: form-data; name="pool_place[Abelson_2852.jpg]"

1
-----------------------------3805226668837
Content-Disposition: form-data; name="mediatype[Abelson_2852.jpg]"

3
-----------------------------3805226668837
Content-Disposition: form-data; name="pool[Abelson_3160-1.jpg]"

general_pool
-----------------------------3805226668837
Content-Disposition: form-data; name="pool_place[Abelson_3160-1.jpg]"

1
-----------------------------3805226668837
Content-Disposition: form-data; name="mediatype[Abelson_3160-1.jpg]"

3
-----------------------------3805226668837
Content-Disposition: form-data; name="files[]"; filename="Abelson_2834.jpg"
Content-Type: image/jpeg

所以“pool”是一个数组，其键设置为名称，其值设置为字符串。

从基本上看起来像这样的形式

我尝试了几种方法来提取信息，但缺点是我必须能够知道关键是什么，这样我才能测试它，这样我就知道我得到了价值。我对发布数据没有选择权，就这样被卡住了。我不能使用 .ToDictionary 之类的东西，因为我也被困在 .net 2.0 中。

这是通过 KeyValuePair 获取正确信息的尝试，你是的，这是错误的，但至少我希望它能够给出需要发生的事情的想法。

media.file_name = "Abelson_2834.jpg"; // test value to pin to
int type = 3;
// NOTE I KNOW KeyValuePair IS NOT RIGHT.. looking for right way thou
foreach (KeyValuePair<string, string> obj in Request.Params["mediatype"])
{
    if( obj.Key == media.file_name ){
        type =  int.Parse(obj.Value); 
        // value of type should be 3 since there is a 
        // Request.Params["mediatype"]["Abelson_2834.jpg"] but since you can't call keys
        // by name it thnk it should be an int
        // like Request.Params["mediatype"][0]
    }
}

media.type = ActiveRecordBase<media_types>.Find(type);
ActiveRecordMediator<media_repo>.Save(media);

有人对如何使这项工作有想法吗？我认为将 String[] 转换为 Dictionary 或 Hashtable 将是诀窍，但是.. 到目前为止它还没有工作。

感谢您的帮助。干杯，杰里米巴斯

旁注如果这是 php，我只需要去

$value = $_POST["mediatype"]["Abelson_2834.jpg"];

如果可以解决一些问题，我将拥有所需的价值。

输入会误导您。您实际上正在获取属性 [对象] = 值。如果您使用 Key = some_function(object,property), Value=value 创建 KVP，您将朝着正确的方向前进。例如，作为上述代码的一次性：

 if (!String.IsNullOrEmpty(Request.Params["mediatype"])){
        foreach (KeyValuePair<string, string> obj in Request.Params["mediatype"])
        {
           dict_props[obj.Key+"_mediatype"]=value;
           // add each object to a list
        }
 }
 // for each object in the list
 //    for each property
 ...process dictionary....

解决方案是这样的

media.file_name = "Abelson_2834.jpg";
int type = 3;
int tmp = int.Parse(Request.Params["mediatype[" + media.file_name+ "]"]);
if(tmp>0){
    type = tmp;
}

简而言之，您需要直接针对第一级表单键，因为 C# .net 2.0 至少不明白来自帖子的数组可以具有除 int 之外的键。当它看到这一点时，它所做的就是将其视为一个字符串，因此，您将其称为一个字符串。

谢谢你们的帮助。干杯-杰里米
