How to Use C# Code in XmlTextWriter

Reading and writing XML is a convenient way to format records. The standard has made it easy for developers to communicate across platforms and services. XMLTextWriter is a class in C# that allows programmers to write XML files. These files can be picked up and read by other applications or even web browsers. Using the class takes a only few lines of code to create dynamic files.

Instructions

1. Import the XML namespace library. This namespace is a part of the ASP.NET platform. Include this library at the top of your code to use the XMLTextWriter class. The code below calls the library that contains the class.
   using System.Xml;

2. Instantiate the class and assign it to a variable. To use XMLTextWriter, a variable needs to contain it to use the methods and properties. The code below accomplishes instantiating the class and creating the file on the computer.
   XmlTextWriter myFile= new XmlTextWriter(@"myXMLFile.xml", System.Text.Encoding.UTF8);

3. Prepare the file for writing and set up the initial dataset tag. After declaring the myFile variable, the "WriteStartDocument()" needs to be called. The initial tag is written to the file to give the dataset a name.
   myFile.WriteStartDocument();
   myFile.WriteStartElement("TheRecords);

4. Write the dataset tags and definitions to the XML file. For this example, the use of "employee" sets up the group of records that contains the employee list.
   myFile.WriteStartElement("Employee");
   myFile.WriteElementString("ID", "123");

5. Write the end tag for the employee records and close the document. The "WriteEndElement()" method closes the document tag. This is important for proper XML format. After the application is finished writing to the file, it needs to be closed for other processes to use.
   myFile.WriteEndElement();
   myFile.WriteEndDocument();

6. Flush the file and release the document. The "Flush()" method takes the text contained in memory and writes it to the file. "Close()" completely releases the file from memory so other applications or users can open the file.
   myFile.Flush();
   myFile.Close();
