Examples

Shows how to format field results.

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

// Use a document builder to insert a field that displays a result with no format applied.
Field field = builder.InsertField("= 2 + 3");

Assert.AreEqual("= 2 + 3", field.GetFieldCode());
Assert.AreEqual("5", field.Result);

// We can apply a format to a field's result using the field's properties.
// Below are three types of formats that we can apply to a field's result.
// 1 -  Numeric format:
FieldFormat format = field.Format;
format.NumericFormat = "$###.00";
field.Update();

Assert.AreEqual("= 2 + 3 \\# $###.00", field.GetFieldCode());
Assert.AreEqual("$  5.00", field.Result);

// 2 -  Date/time format:
field = builder.InsertField("DATE");
format = field.Format;
format.DateTimeFormat = "dddd, MMMM dd, yyyy";
field.Update();

Assert.AreEqual("DATE \\@ \"dddd, MMMM dd, yyyy\"", field.GetFieldCode());
Console.WriteLine($"Today's date, in {format.DateTimeFormat} format:\n\t{field.Result}");

// 3 -  General format:
field = builder.InsertField("= 25 + 33");
format = field.Format;
format.GeneralFormats.Add(GeneralFormat.LowercaseRoman);
format.GeneralFormats.Add(GeneralFormat.Upper);
field.Update();

int index = 0;
using (IEnumerator<GeneralFormat> generalFormatEnumerator = format.GeneralFormats.GetEnumerator())
    while (generalFormatEnumerator.MoveNext())
        Console.WriteLine($"General format index {index++}: {generalFormatEnumerator.Current}");

Assert.AreEqual("= 25 + 33 \\* roman \\* Upper", field.GetFieldCode());
Assert.AreEqual("LVIII", field.Result);
Assert.AreEqual(2, format.GeneralFormats.Count);
Assert.AreEqual(GeneralFormat.LowercaseRoman, format.GeneralFormats[0]);

// We can remove our formats to revert the field's result to its original form.
format.GeneralFormats.Remove(GeneralFormat.LowercaseRoman);
format.GeneralFormats.RemoveAt(0);
Assert.AreEqual(0, format.GeneralFormats.Count);
field.Update();

Assert.AreEqual("= 25 + 33  ", field.GetFieldCode());
Assert.AreEqual("58", field.Result);
Assert.AreEqual(0, format.GeneralFormats.Count);
