    IWSection section = document.AddSection();
    IWParagraph paragraph = section.AddParagraph();
    paragraph.AppendText("If field which uses string of characters in expression");
    paragraph = section.AddParagraph();
    //Create the new instance of IF field
    WIfField field = paragraph.AppendField("If", FieldType.FieldIf) as WIfField;
    //Specify the expression, true and false statement in field code
    field.FieldCode = "IF \"True\" = \"True\" \"The given statement is Correct\" \"The given statement is Wrong\"";
    paragraph = section.AddParagraph();
    paragraph.AppendText("If field which uses numbers in expression");
    paragraph = section.AddParagraph();
    //Create the new instance of IF field
    field = paragraph.AppendField("If", FieldType.FieldIf) as WIfField;
    //Specify the expression, true and false statement in field code
    field.FieldCode = "IF 100 >= 1000 \"The given statement is Correct\" \"The given statement is Wrong\"";
    //Update the document fields
    document.UpdateDocumentFields();
    document.Save("Sample.docx", FormatType.Docx);
    document.Close();
}
Private Sub button_Click(sender As Object, e As EventArgs)
    Dim document As New WordDocument()
    Dim section As IWSection = document.AddSection()
    Dim paragraph As IWParagraph = section.AddParagraph()
    paragraph.AppendText("If field which uses string of characters in expression")
    paragraph = section.AddParagraph()
    'Create the new instance of IF field
    Dim field As WIfField = TryCast(paragraph.AppendField("If", FieldType.FieldIf), WIfField)
    'Specify the expression, true and false statement in field code
    field.FieldCode = "IF ""True"" = ""True"" ""The given statement is Correct"" ""The given statement is Wrong"""
