How to change number of characters used for indentation when writing XML with XDocument in C#

In C#, you can change the number of characters used for indentation when writing XML with XDocument by setting the XDocument.SaveOptions property. The SaveOptions property is an enumeration that allows you to customize various aspects of XML serialization.

To change the number of characters used for indentation, you can set the SaveOptions.Indent property to true and the SaveOptions.IndentChars property to a string containing the desired number of spaces or tabs. Here's an example:

XDocument doc = new XDocument( new XElement("Root", new XElement("Child", "Value") ) ); doc.SaveOptions = new XmlWriterSettings { Indent = true, IndentChars = "\t" }; string xml = doc.ToString();

In this example, we create an XDocument object that contains a root element and a child element. We then set the SaveOptions property to a new XmlWriterSettings object that has the Indent property set to true and the IndentChars property set to a tab character.

Finally, we call the ToString method of the XDocument object to get the serialized XML string.

Note that this is just an example, and you should customize the XDocument creation and serialization according to your own requirements. Also, note that the SaveOptions property is only available in .NET Framework 4.5 and later, and .NET Core 1.0 and later.

Examples

  1. "C# XDocument change XML indentation size"

    • Code:
      XDocument document = new XDocument(new XElement("Root", new XElement("Element", "Value"))); XmlWriterSettings settings = new XmlWriterSettings { Indent = true, IndentChars = " " }; // Set the number of spaces using (XmlWriter writer = XmlWriter.Create("output.xml", settings)) { document.Save(writer); }
    • Description: Uses XmlWriterSettings to set the number of spaces used for indentation.

  2. "C# XDocument change XML indentation to tabs"

    • Code:
      XDocument document = new XDocument(new XElement("Root", new XElement("Element", "Value"))); XmlWriterSettings settings = new XmlWriterSettings { Indent = true, IndentChars = "\t" }; // Use tabs for indentation using (XmlWriter writer = XmlWriter.Create("output.xml", settings)) { document.Save(writer); }
    • Description: Configures XmlWriterSettings to use tabs for indentation.

  3. "C# XDocument change XML indentation size dynamically"

    • Code:
      int indentationSize = 2; // Set the desired indentation size XDocument document = new XDocument(new XElement("Root", new XElement("Element", "Value"))); XmlWriterSettings settings = new XmlWriterSettings { Indent = true, IndentChars = new string(' ', indentationSize) }; using (XmlWriter writer = XmlWriter.Create("output.xml", settings)) { document.Save(writer); }
    • Description: Dynamically sets the indentation size based on a variable.

  4. "C# XDocument save with minimal XML indentation"

    • Code:
      XDocument document = new XDocument(new XElement("Root", new XElement("Element", "Value"))); XmlWriterSettings settings = new XmlWriterSettings { Indent = false }; // Disable indentation using (XmlWriter writer = XmlWriter.Create("output.xml", settings)) { document.Save(writer); }
    • Description: Disables XML indentation by setting Indent to false.

  5. "C# XDocument change XML formatting to compact"

    • Code:
      XDocument document = new XDocument(new XElement("Root", new XElement("Element", "Value"))); XmlWriterSettings settings = new XmlWriterSettings { NewLineChars = "", Indent = false }; // Compact formatting using (XmlWriter writer = XmlWriter.Create("output.xml", settings)) { document.Save(writer); }
    • Description: Configures XmlWriterSettings for compact XML formatting without indentation.

  6. "C# XDocument change XML indentation in memory"

    • Code:
      XDocument document = new XDocument(new XElement("Root", new XElement("Element", "Value"))); XmlWriterSettings settings = new XmlWriterSettings { Indent = true, IndentChars = " " }; StringWriter stringWriter = new StringWriter(); using (XmlWriter writer = XmlWriter.Create(stringWriter, settings)) { document.Save(writer); } string xmlString = stringWriter.ToString();
    • Description: Saves the XDocument with the specified indentation settings in memory.

  7. "C# XDocument change XML indentation using StringBuilder"

    • Code:
      XDocument document = new XDocument(new XElement("Root", new XElement("Element", "Value"))); XmlWriterSettings settings = new XmlWriterSettings { Indent = true, IndentChars = " " }; StringBuilder stringBuilder = new StringBuilder(); using (XmlWriter writer = XmlWriter.Create(stringBuilder, settings)) { document.Save(writer); } string xmlString = stringBuilder.ToString();
    • Description: Uses a StringBuilder to store the XML with the specified indentation.

  8. "C# XDocument change XML indentation for specific element"

    • Code:
      XElement element = new XElement("Element", "Value"); element.Add(new XAttribute("attribute", "AttributeValue")); XDocument document = new XDocument(new XElement("Root", element)); XmlWriterSettings settings = new XmlWriterSettings { Indent = true, IndentChars = " " }; using (XmlWriter writer = XmlWriter.Create("output.xml", settings)) { document.Save(writer); }
    • Description: Configures indentation for a specific element within the XDocument.

  9. "C# XDocument change XML indentation globally"

    • Code:
      XDocument document = new XDocument(new XElement("Root", new XElement("Element", "Value"))); XDocument.GlobalOptions.Indent = true; XDocument.GlobalOptions.IndentChars = " "; document.Save("output.xml");
    • Description: Changes the global XDocument options for indentation.

  10. "C# XDocument change XML indentation with custom formatting"

    • Code:
      XDocument document = new XDocument(new XElement("Root", new XElement("Element", "Value"))); XmlWriterSettings settings = new XmlWriterSettings { Indent = true, IndentChars = " ", NewLineChars = "\r\n", // Custom newline characters }; using (XmlWriter writer = XmlWriter.Create("output.xml", settings)) { document.Save(writer); }
    • Description: Customizes XML formatting with both indentation and custom newline characters.
