Serialization and Deserialization Problem

[nikitenko@dataart.com]

I faced to problem. Firstly I used trial teechart in my application (vesion 2.0.2040.15118). I saved chart into file using next code

protected Steema.TeeChart.TChart chart;
public override void GetObjectData(SerializationInfo info, StreamingContext context)
{
info.AddValue("chart", chart);
}

After that I uninstalled trial version and installed license teechart (version 2.0.2179.21172). Than I rebuilt my application using new teechart, then I tried to restore saved before chart.

fileStream = File.Open(fileName, FileMode.Open, FileAccess.ReadWrite);
SoapFormatter serializer = new SoapFormatter();
Some_type some_type = (Some_type)serializer.Deserialize(fileStream);

there is an error!!!
"Parse Error, no assembly associated with Xml key a11:http://schemas.microsoft.com/clr/nsasse ... 276c77bdb7 TChart"
As I understand it has happened due to the fact the application cann't
find required assembly.

Please, any idea to resolve this problem.

Thanks.

I've done some research and found out that two version TeeChart.dll have defferent implementation DeserializeFrom method, namely

old version
....
else if (descriptor3.PropertyType == typeof(StringList))
{
StringList list2 = new StringList(((Array) entry2.Value).Length);
list2.AddRange((Array) entry2.Value);
if (list2.Count > 0)
{
descriptor3.SetValue(obj2, list2);
}
}
....

and new one

......
else if (descriptor3.PropertyType == typeof(StringList))
{
StringList list2 = new StringList(((StringList) entry2.Value).Count);
list2.AddRange((StringList) entry2.Value);
if (list2.Count > 0)
{
descriptor3.SetValue(obj2, list2);
}
}
.....

May be it is a bug. But I don't know how to resolve it.

Hello,

Have you tried TeeChart native file exporting and importing as told in Tutorial 12 - Exporting and Importing Charts? TeeChart tutorials can be found at its program group.
