SerializeTagEventArgs.Context Property

Gets a context object that can help you write and read various values.

Namespace: MindFusion.Scheduling
Assembly: MindFusion.Scheduling

 Syntax

C#

public XmlSerializationContext Context { get; }

Visual Basic

Public ReadOnly Property Context As XmlSerializationContext

 Property Value

An instance of the XmlSerializationContext class.

 Remarks

It is recommended to operate with the underlying XML document by calling the methods of this object. See the example section below for a demonstration on how to use this object.

 Example

The following example demonstrates how to use the Context object in order to write and read complex tag values in the XML document.

C#

class MyTag
{
    public MyTag(int intValue, string stringValue)
    {
        IntValue = intValue;
        StringValue = stringValue;
}

    public int IntValue;
    public string StringValue;
}

// ...

private void OnSerializeTag(object sender, SerializeTagEventArgs e)
{
    if (e.Tag is MyTag)
    {
        e.Handled = true;
        e.Context.WriteBool(true, "mytag", e.Representation);

        MyTag tag = e.Tag as MyTag;
        e.Context.WriteInt(tag.IntValue, "intValue", e.Representation);
        e.Context.WriteString(tag.StringValue, "stringValue", e.Representation);
    }
}

private void OnDeserializeTag(object sender, SerializeTagEventArgs e)
{
    if (e.Context.ReadBool("mytag", e.Representation, false))
    {
        e.Handled = true;

        int intValue = e.Context.ReadInt("intValue", e.Representation);
        string stringValue = e.Context.ReadString("stringValue", e.Representation);

        e.Tag = new MyTag(intValue, stringValue);
    }
}

Visual Basic

Class MyTag

    Public Sub New(ByVal intValue As Integer, ByVal stringValue As String)

        IntValue = intValue;
        StringValue = stringValue;

    End Sub

    Public IntValue As Integer
    Public StringValue As String

End Class

Private Sub OnSerializeTag(ByVal sender As Object, ByVal e As SerializeTagEventArgs)

    If TypeOf e.Tag Is MyTag Then

        e.Handled = True
        e.Context.WriteBool(True, "mytag", e.Representation)

        Dim tag As MyTag = CType(e.Tag, MyTag)
        e.Context.WriteInt(tag.IntValue, "intValue", e.Representation)
        e.Context.WriteString(tag.StringValue, "stringValue", e.Representation)

    End If

End Sub

Private Sub OnDeserializeTag(ByVal sender As Object, ByVal e As SerializeTagEventArgs)

    If e.Context.ReadBool("mytag", e.Representation, False) Then

        e.Handled = True

        Dim intValue As Integer = e.Context.ReadInt("intValue", e.Representation)
        Dim stringValue As String = e.Context.ReadString("stringValue", e.Representation)

        e.Tag = New MyTag(intValue, stringValue)

    End If

End Sub
