    <p>There is an error very simple to reproduce when serializing and deserializing with different .net frameworks (framework 2 and 4). When I serialize a System.Globalization.CompareInfo with framework 2 and try to deserialize it with framework 4 there will be an OverflowException. The code is as follows:</p> <pre><code>private void button1_Click(object sender, EventArgs e) { CompareInfo ci = CompareInfo.GetCompareInfo("de-DE"); Stream stream = File.Open("C:\\Temp\\test.bin", FileMode.Create); BinaryFormatter formatter = new BinaryFormatter(); formatter.AssemblyFormat = System.Runtime.Serialization.Formatters.FormatterAssemblyStyle.Simple; formatter.TypeFormat = System.Runtime.Serialization.Formatters.FormatterTypeStyle.XsdString; formatter.Serialize(stream, ci); stream.Close(); } private void button2_Click(object sender, EventArgs e) { Stream stream = File.Open("C:\\Temp\\test.bin", FileMode.Open); BinaryFormatter formatter = new BinaryFormatter(); CompareInfo ci = (CompareInfo)formatter.Deserialize(stream); stream.Close(); } </code></pre> <p>When I do this with the same version (2 or 4) it works as expected. When I save the file with framework 2 and try to open it with framework 4 i will get the OverflowException. Now I am looking for a workaround (since there are thousands of files writen with framework 2.0 at our customers). I tried an approach like in <a href="https://stackoverflow.com/questions/2174591/net-c-how-to-add-a-custom-serialization-attribute-that-acts-as-iserializable">How to add a custom serialization attribute that acts as ISerializable interface</a> but with no success. Any Ideas?</p> <p>I am sorry, I omitted the two lines that made may code crash:</p> <pre><code> formatter.AssemblyFormat = System.Runtime.Serialization.Formatters.FormatterAssemblyStyle.Simple; formatter.TypeFormat = System.Runtime.Serialization.Formatters.FormatterTypeStyle.XsdString; </code></pre> <p>because I thought they were not necessary. Now I updated the code and it is crashing. It doesn't help to include these lines when reading the file.</p>

    1. COI've just tried exactly what you say (serialize in 2.0.50727.6400, deserialize in 4.0.30319.18010, using the code you've posted) - and it worked fine...

    2. COThanks for trying, it doesn't work for me. I am using VisualStudio 2010, I boiled down this code in the most simple WindowsForms application with two buttons. If I press button_1 with framework 2, then change to framework 4, recompile and press button_2, I get the overflow exception. Ofcourse I discovered this bug only until customers came with files they couldn't open with the new (framework 4) based version of our software. I couldn't open them either, finally find out it was the CompareInfo object and tried to reproduce it with the most simple scenario.

    3. COSorry Marc, you were right, I edited my question. Now it is crashing again. Unfortunately I cannot change the old code, the files have been saved long time ago...

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
