Hi Jialiang,
I am developing a web application and I have to put this dataset in asp.net in-memory session.
I am concern about the web server memory that this dataset might occupy.
The memory that a dataset occupies might not be equal with the size of the dataset's serialization result (am I wrong?)
Is there any technique to analyze the amt of RAM memory that a dataset occupies?
Thank you,
Max

Hello Max,.
I assume that you meant the size of the dataset's serialization result by
"the size of a dataset (including data in the data tables and rows). The
answer depends on the serialization format:
If we use BinaryFormatter, Code list 1 shows the pseudocode:
---Code list 1 ---
DataSet ds = GetData();
ds.RemotingFormat = SerializationFormat.Binary;
BinaryFormatter bin = new BinaryFormatter();
bin.Serialize(stream, ds);
Console.Write(stream.Length);
If we serialize the dataset to XML, we can do it in this way:
---Code list 2 ---
DataSet ds = GetData();
Console.Write(Encoding.UTF8.GetByteCount(ds.GetXml()));
For more information of DataSet Serialization, please refer to the articles:

If you have any other questions or concerns, please DON'T hesitate to tell
