API Utilization from .NET Using WebClient - Posting Arrays (ex: customfields)

[aptinno]

Hello,

 

I have made a wrapper for the API in C#, which I plan on making available to the community as an open source project.

 

I seem to be having issues posting base64 encoded serialized arrays, like those used for "customfields".

 

I've read other posts and see that many users have had inquiries on this issue. I understand that the in the case of "customfields", the NameValueCollection's name (key) should correspond to the "Custom Field Id", however my posted data is still being ignored.

 

Anyone have an example of posting the base64 encoded serialized arrays using .NET's WebClient? I have attempted to, both, base64 encode a serialized NameValueCollection (example 1), as well as adding each field explicitly (example 2)-- neither seems to work.

 

 

NameValueCollection nvp = new NameValueCollection();
nvp.Add("username", "xxx");
nvp.Add("password", "xxx");
nvp.Add("action", "xxx");
...

// add custom fields
NameValueCollection customFields = new NameValueCollection();
customFields.Add("1", "Field1 Value");
customFields.Add("2", "Field2 Value");

nvp.Add("customfields", SerializeBase64(customFields));
WebClient client = new WebClient();
client.UploadValues("url", nvp);

 

       public static string SerializeBase64(object o)
       {
           // Serialize to a base 64 string
           byte[] bytes;
           long length = 0;
           MemoryStream ws = new MemoryStream();
           BinaryFormatter sf = new BinaryFormatter();
           sf.Serialize(ws, o);
           length = ws.Length;
           bytes = ws.GetBuffer();
           string encodedData = bytes.Length + ":" + Convert.ToBase64String(bytes, 0, bytes.Length, Base64FormattingOptions.None);
           return encodedData;
       }

 

 

Example 2

 

NameValueCollection nvp = new NameValueCollection();
nvp.Add("action", "xxx");
nvp.Add("customfields[1]", "value");
// nvp.Add("customfields["1"]", "value");   // also tried

WebClient client = new WebClient();
client.UploadValues("url", nvp);

 

 

Thank you in advance.
