XmlWriter.WriteValue Method (DateTime)

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Writes a DateTime value.

Namespace:  System.Xml
Assembly:  System.Xml (in System.Xml.dll)

Syntax

'Declaration
Public Overridable Sub WriteValue ( _
    value As DateTime _
)

public virtual void WriteValue(
    DateTime value
)

Parameters

Exceptions

Exception Condition
ArgumentException

An invalid value was specified.

Remarks

If WriteValue is called multiple times in succession, the values are not delimited by a space. You must call WriteWhitespace between calls to WriteValue to insert white space. Pass an array type to the XmlWriter.WriteValue(Object) overload to write out an array of distinct values.

If this method is called on an XmlWriter instance that outputs text-only, the typed value is serialized to text.

Examples

Dim output As New StringBuilder()

Dim price As Double = 9.95
Dim [date] As New DateTime(2004, 5, 20)

Using writer As XmlWriter = XmlWriter.Create(output)
    writer.WriteStartElement("book")
    writer.WriteStartAttribute("pub-date")
    writer.WriteValue([date])
    writer.WriteEndAttribute()

    writer.WriteStartElement("price")
    writer.WriteValue(price)
    writer.WriteEndElement()

    writer.WriteEndElement()
    writer.Flush()
End Using

OutputTextBlock.Text = output.ToString()


StringBuilder output = new StringBuilder();

Double price = 9.95;
DateTime date = new DateTime(2004, 5, 20);

using (XmlWriter writer = XmlWriter.Create(output))
{
    writer.WriteStartElement("book");
    writer.WriteStartAttribute("pub-date");
    writer.WriteValue(date);
    writer.WriteEndAttribute();

    writer.WriteStartElement("price");
    writer.WriteValue(price);
    writer.WriteEndElement();

    writer.WriteEndElement();
    writer.Flush();
}

OutputTextBlock.Text = output.ToString();
