I have a client/server project and I m trying to send via socket a DataTable(extracted from a TableAdapter) from server to client. My server namespace is srvCentral and my client is appClient. When I try to deserialize DataTable in client it throws me an Serialize Exception saying Unable to find assembly srvCentral, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null I ve googled and tryed things like controlling the AssemblyResolve, that makes svchost hang and force me to close, and using a binder like this:

sealed class AllowAllAssemblyVersionsDeserializationBinder : SerializationBinder
{
    public override Type BindToType(string assemblyName, string typeName)
    {
        Type typeToDeserialize = null;

        String currentAssembly = Assembly.GetExecutingAssembly().FullName;

        // In this case we are always using the current assembly
        assemblyName = currentAssembly;

        // Get the type using the typeName and assemblyName
        typeToDeserialize = Type.GetType(String.Format("{0}, {1}",
                                         typeName, assemblyName));

        return typeToDeserialize;
    }
}

And the exception stills there... Wasn t it suppose to DataTable be Deserializable anywhere? What am I doing wrong?

我的序列代号是:

public byte[] Serializar(Object item)
{
    BinaryFormatter formatter = new BinaryFormatter();
    MemoryStream ms = new MemoryStream();
    formatter.Serialize(ms, item);
    return ms.ToArray();
}

public Object Deserializar(byte[] buffer)
{
    BinaryFormatter formatter = new BinaryFormatter();
    MemoryStream ms = new MemoryStream(buffer);

    formatter.AssemblyFormat = System.Runtime.Serialization.Formatters.FormatterAssemblyStyle.Simple;

    formatter.Binder = new AllowAllAssemblyVersionsDeserializationBinder();

    Object a = formatter.Deserialize(ms);

    return a;
}

sealed class AllowAllAssemblyVersionsDeserializationBinder : SerializationBinder
{
    public override Type BindToType(string assemblyName, string typeName)
    {
        Type typeToDeserialize = null;

        String currentAssembly = Assembly.GetExecutingAssembly().FullName;

        // In this case we are always using the current assembly
        assemblyName = currentAssembly;

        // Get the type using the typeName and assemblyName
        typeToDeserialize = Type.GetType(String.Format("{0}, {1}",
                                         typeName, assemblyName));

        return typeToDeserialize;
    }
}

这不是解决问题的最好办法,而是避免问题的简单办法。对于小东西来说,就足够了。如果你想从表格中获取数据只显示内容,请使用此方法。

namespace YourLibrary
{
[Serializable]
public class Tabela: ISerializable
{
    protected ArrayList colNames;
    protected ArrayList colTypes;
    protected ArrayList dataRows;

    public Tabela()
    {

    }

    public Tabela (DataTable dt)
    {
        colNames = new ArrayList();
        colTypes = new ArrayList();
        dataRows = new ArrayList();
        // Insert column information (names and types)
        foreach(DataColumn col in dt.Columns)
        {
            colNames.Add(col.ColumnName); 
            colTypes.Add(col.DataType.FullName);   
        }

        // Insert rows information
        foreach(DataRow row in dt.Rows)
            dataRows.Add(row.ItemArray);
    }

    public Tabela(SerializationInfo info, StreamingContext context)
    {
        colNames = (ArrayList)info.GetValue("colNames",typeof(ArrayList));
        colTypes = (ArrayList)info.GetValue("colTypes",typeof(ArrayList));
        dataRows = (ArrayList)info.GetValue("dataRows",typeof(ArrayList));

    }

    void ISerializable.GetObjectData(SerializationInfo info, StreamingContext context)
    {
        info.AddValue("colNames", colNames);
        info.AddValue("colTypes", colTypes);
        info.AddValue("dataRows", dataRows);
    }

    public DataTable GenerateDataTable()
    {
        DataTable dt = new DataTable();

        // Add columns
        for(int i=0; i<colNames.Count; i++)
        {
            DataColumn col = new DataColumn(colNames[i].ToString(), 
                Type.GetType(colTypes[i].ToString() ));     
            dt.Columns.Add(col);
        }

        // Add rows
        for(int i=0; i<dataRows.Count; i++)
        {
            DataRow row = dt.NewRow();
            row.ItemArray = (object[]) dataRows[i];
            dt.Rows.Add(row);
        }

        dt.AcceptChanges();
        return dt;
    }
}
}
