How to read barcode value from pdf file using c# ?? Pin. XmlTextWriter provides three constructors; the constructor arguments identify the destination where the XmlTextWriter should write to as well as the encoding to use. These constructors are summarized in Table 11-14. This code generates the following output: empid ----------1 2 3 4 5 6 7 8 9 10 11 12 13 14 lvl ----------0 1 1 2 2 2 2 3 3 3 3 4 4 4 path -----------------.1. .1.2. .1.3. .1.2.4. .1.2.5. .1.2.6. .1.3.7. .1.2.5.8. .1.3.7.9. .1.2.5.10. .1.3.7.11. .1.3.7.9.12. .1.3.7.9.13. .1.3.7.9.14. Constructor Comments XmlTextWriter(TextWriter) Creates an XmlTextWriter that writes to the specified System.IO.TextWriter. Uses the encoding configured on the TextWriter instance. Creates an XmlTextWriter that writes to a System.IO.Stream XmlTextWriter(Stream, using the specified System.Text.Encoding. If the Encoding Encoding) argument is null, the default is UTF-8 encoding. Creates an XmlTextWriter that writes to the file with the name XmlTextWriter(string, specified in the string argument using the System.Text.Encoding Encoding) provided. If the Encoding argument is null, the default is UTF-8 encoding. The XmlTextWriter overwrites the file if it exists. 12 foreach (DataTable t in ds.Tables) { Console.WriteLine("Table " + t.TableName + " is in dataset"); Console.WriteLine("Row 0, column 1: " + t.Rows[0][1]); Console.WriteLine("Row 1, column 1: " + t.Rows[1][1]); Console.WriteLine("Row 2, column 1: " + t.Rows[2][1]); } ds.WriteXml("dataset.xml"); ds.WriteXmlSchema("dataset.xsd"); // Also may bind to the tables here: ; With both the lvl and path values, you can easily return output that graphically shows the hierarchical relationships of the employees in the subtree: The XmlTextWriter.BaseStream property returns the underlying Stream used for output. If the XmlTextWriter was created from a TextWriter that doesn't derive from System.IO.StreamWriter, null is returned.
