Shows how to import a style from one document into a different document.

Document srcDoc = new Document();

// Create a custom style for the source document.
Style srcStyle = srcDoc.Styles.Add(StyleType.Paragraph, "MyStyle");
srcStyle.Font.Color = Color.Red;

// Import the source document's custom style into the destination document.
Document dstDoc = new Document();
Style newStyle = dstDoc.Styles.AddCopy(srcStyle);

// The imported style has an appearance identical to its source style.
Assert.AreEqual("MyStyle", newStyle.Name);
Assert.AreEqual(Color.Red.ToArgb(), newStyle.Font.Color.ToArgb());

Shows how to clone a document’s style.

Document doc = new Document();

// The AddCopy method creates a copy of the specified style and
// automatically generates a new name for the style, such as "Heading 1_0".
Style newStyle = doc.Styles.AddCopy(doc.Styles["Heading 1"]);

// Use the style's "Name" property to change the style's identifying name.
newStyle.Name = "My Heading 1";

// Our document now has two identical looking styles with different names.
// Changing settings of one of the styles do not affect the other.
newStyle.Font.Color = Color.Red;

Assert.AreEqual("My Heading 1", newStyle.Name);
Assert.AreEqual("Heading 1", doc.Styles["Heading 1"].Name);

Assert.AreEqual(doc.Styles["Heading 1"].Type, newStyle.Type);
Assert.AreEqual(doc.Styles["Heading 1"].Font.Name, newStyle.Font.Name);
Assert.AreEqual(doc.Styles["Heading 1"].Font.Size, newStyle.Font.Size);
Assert.AreNotEqual(doc.Styles["Heading 1"].Font.Color, newStyle.Font.Color);
