Examples

Shows how to compare expressions using a COMPARE field.

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

FieldCompare field = (FieldCompare)builder.InsertField(FieldType.FieldCompare, true);
field.LeftExpression = "3";
field.ComparisonOperator = "<";
field.RightExpression = "2";
field.Update();

// The COMPARE field displays a "0" or a "1", depending on its statement's truth.
// The result of this statement is false so that this field will display a "0".
Assert.AreEqual(" COMPARE  3 < 2", field.GetFieldCode());
Assert.AreEqual("0", field.Result);

builder.Writeln();

field = (FieldCompare)builder.InsertField(FieldType.FieldCompare, true);
field.LeftExpression = "5";
field.ComparisonOperator = "=";
field.RightExpression = "2 + 3";
field.Update();

// This field displays a "1" since the statement is true.
Assert.AreEqual(" COMPARE  5 = \"2 + 3\"", field.GetFieldCode());
Assert.AreEqual("1", field.Result);

doc.UpdateFields();
doc.Save(ArtifactsDir + "Field.COMPARE.docx");
