[英]How to send soap with an image attachement in vb6 to a web service in c# with MTOM?
There is my code: 有我的代码:
=> Part of my web.config (c#): =>我的web.config(c#)的一部分:
<basicHttpBinding>
<binding name="secureHttpBinding"
maxReceivedMessageSize="2097152" messageEncoding="Mtom"
transferMode="Streamed">
<readerQuotas maxStringContentLength="2097152" maxArrayLength="2097152" />
<security mode="Transport">
<transport clientCredentialType="None"/>
</security>
</binding>
</basicHttpBinding>
=> Function I want to call (c#): =>我要调用的函数(C#):
[OperationContract]
[WebInvoke(RequestFormat = WebMessageFormat.Xml, ResponseFormat = WebMessageFormat.Xml, Method = "POST", BodyStyle = WebMessageBodyStyle.WrappedRequest)]
ImageData UploadImage(string clientAppKey, string organizationId, string name, byte[] value);
=> My soap I try to send (vb6): =>我尝试发送的肥皂(vb6):

[My bytes array??]
--uuid:d2d519f9-a921-436c-95b0-e31576611a01+id=16
There is my problem: 我的问题是:
I received my data in c#, but the bytes array I received is not good. 我在c#中收到了数据,但是收到的字节数组不好。
I try many way to send my byte array. 我尝试了多种发送字节数组的方法。
1- I try in base64 but the bytes array in c# is longer than my bytes array in vb6. 1-我尝试在base64中使用,但C#中的字节数组比vb6中的字节数组长。 example: I send a byte array of 40000 in vb6 and got a array of 50000 in c#.
示例:我在vb6中发送了一个40000的字节数组,在c#中得到了50000的一个数组。
2- I try in string unicode but the array was too short. 2-我尝试使用字符串unicode,但是数组太短。 example: I send StrConv(b(), vbUnicode) and got a array of 8 in c#.
示例:我发送StrConv(b(),vbUnicode)并在c#中得到8的数组。 UBound(b) = 40000
磅(b)= 40000
My question is how I send my byte array in vb6 to get the same array in c#? 我的问题是我如何在vb6中发送字节数组以在c#中获得相同的数组?
Thanks for your time. 谢谢你的时间。
Finally, I found a way that it work. 最终,我找到了一种可行的方法。
I send my byte array in base64 and convert in c#. 我在base64中发送字节数组,然后在c#中进行转换。
value = Convert.FromBase64String(Encoding.UTF8.GetString(value));
The solution with StrConv(b(), vbUnicode) not working because when c# read my string it stop reading on char 0. StrConv(b(),vbUnicode)的解决方案不起作用,因为当c#读取我的字符串时,它将停止读取char 0。
