| Guest | WCF RC1: having problem with the DataContract attribute Hi, I'm building a small application that can send data between servers. The Data object is a simple class with 3 properties (2 strings, and a byte[] array). If I add [DataMember] over each properties, the call to the remote server throw an error : 400 Bad Request (I'm using the wsHttpBinding). If I remove the [DataMember] attribute, the remote method is reached, but each properties of my object is "null" (normal since the datamember attribute is not set). As I said in a previous post, the server sometimes acts as client, sometimes act as server. Then I don't use a proxy created by VS, but a ChannelFactory. What is wrong ? Thanks in advance for any help... Steve [DataContract] public class MyDataClass { private byte[] m_bytes; [DataMember] public byte[] Bytes { get { return m_bytes; } set { m_bytes= value; } } private string m_string2; [DataMember] public string String2 { get { return m_string2; } set { m_string2= value; } } private string m_string1; [DataMember] public string String1 { get { return m_string1; } set { m_string1= value; } } public MyDataClass( string string1, string string1, byte[] raw ) { this.m_string1= string1; this.m_string1= string1; this.m_raw= raw; } public MyDataClass() { } } |

| Guest | Re: WCF RC1: having problem with the DataContract attribute I found the reason of this error ... The array of byte exceeds 16K, and it is more than what the default behaviour allow. What are the possible solutions ? The byte array was used to embed files... Is there any other better way to transfert file ? (which should be quite large (up to 100 Mo)...
