Checking if an object is a number

January 1, 2023 by Tarik

You will simply need to do a type check for each of the basic numeric types. Here’s an extension method that should do the job: public static bool IsNumber(this object value) { return value is sbyte || value is byte || value is short || value is ushort || value is int || value is … Read more

Using StringWriter for XML Serialization

January 1, 2023 by Tarik

One problem with StringWriter is that by default it doesn’t let you set the encoding which it advertises – so you can end up with an XML document advertising its encoding as UTF-16, which means you need to encode it as UTF-16 if you write it to a file. I have a small class to … Read more

How can I make the xmlserializer only serialize plain xml?

December 31, 2022 by Tarik

To put this all together – this works perfectly for me: // To Clean XML public string SerializeToString<T>(T value) { var emptyNamespaces = new XmlSerializerNamespaces(new[] { XmlQualifiedName.Empty }); var serializer = new XmlSerializer(value.GetType()); var settings = new XmlWriterSettings(); settings.Indent = true; settings.OmitXmlDeclaration = true; using (var stream = new StringWriter()) using (var writer = XmlWriter.Create(stream, … Read more

Why are properties without a setter not serialized

December 25, 2022 by Tarik

It’s a limitation of XmlSerializer it doesn’t serialize read-only properties, what you have done in your second example is essentially the hack to get it to serialize, however, it’s useless if you need it to deserialize later. Alternatively you could switch to using DataContractSerializer, it’s more flexible.

How to serialize an object to XML without getting xmlns=”…”?

December 21, 2022 by Tarik

Ahh… nevermind. It’s always the search after the question is posed that yields the answer. My object that is being serialized is obj and has already been defined. Adding an XMLSerializerNamespace with a single empty namespace to the collection does the trick. In VB like this: Dim xs As New XmlSerializer(GetType(cEmploymentDetail)) Dim ns As New … Read more

.NET XML serialization gotchas? [closed]

December 21, 2022 by Tarik

Another huge gotcha: when outputting XML through a web page (ASP.NET), you don’t want to include the Unicode Byte-Order Mark. Of course, the ways to use or not use the BOM are almost the same: BAD (includes BOM): XmlTextWriter wr = new XmlTextWriter(stream, new System.Text.Encoding.UTF8); GOOD: XmlTextWriter wr = new XmlTextWriter(stream, new System.Text.UTF8Encoding(false)) You can … Read more

Serializing an object as UTF-8 XML in .NET

December 15, 2022 by Tarik

No, you can use a StringWriter to get rid of the intermediate MemoryStream. However, to force it into XML you need to use a StringWriter which overrides the Encoding property: public class Utf8StringWriter : StringWriter { public override Encoding Encoding => Encoding.UTF8; } Or if you’re not using C# 6 yet: public class Utf8StringWriter : … Read more

What is MyAssembly.XmlSerializers.dll generated for?

December 14, 2022 by Tarik

In .NET implementation, the XmlSerializer generates a temporary assembly for serializing/deserializing your classes (for performance reasons). It can either be generated on the fly (but it takes time on every execution), or it can be pregenerated during compilation and saved in this assembly you are asking about. You can change this behaviour in project options … Read more

XmlSerializer: remove unnecessary xsi and xsd namespaces

November 21, 2022 by Tarik

//Create our own namespaces for the output XmlSerializerNamespaces ns = new XmlSerializerNamespaces(); //Add an empty namespace and empty value ns.Add(“”, “”); //Create the serializer XmlSerializer slz = new XmlSerializer(someType); //Serialize the object with our own namespaces (notice the overload) slz.Serialize(myXmlTextWriter, someObject, ns)
