例子
展示如何识别和使用替换模式中的替换。
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
builder.Write("Jason gave money to Paul.");
Regex regex = new Regex(@"([A-z]+) gave money to ([A-z]+)");
FindReplaceOptions options = new FindReplaceOptions();
options.UseSubstitutions = true;
// 使用legacy模式不支持很多高级功能,所以我们需要将其设置为'false'。
options.LegacyMode = false;
doc.Range.Replace(regex, @"$2 took money from $1", options);
Assert.AreEqual(doc.GetText(), "Paul took money from Jason.\f");
展示如何用替换来替换文本。
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
builder.Writeln("John sold a car to Paul.");
builder.Writeln("Jane sold a house to Joe.");
// 我们可以使用“FindReplaceOptions”对象来修改查找和替换过程。
FindReplaceOptions options = new FindReplaceOptions();
// 将“UseSubstitutions”属性设置为“true”即可获取
// 用于识别替换元素的查找和替换操作。
// 将“UseSubstitutions”属性设置为“false”以忽略替换元素。
options.UseSubstitutions = useSubstitutions;
Regex regex = new Regex(@"([A-z]+) sold a ([A-z]+) to ([A-z]+)");
doc.Range.Replace(regex, @"$3 bought a $2 from $1", options);
Assert.AreEqual(
useSubstitutions
? "Paul bought a car from John.\rJoe bought a house from Jane."
: "$3 bought a $2 from $1.\r$3 bought a $2 from $1.", doc.GetText().Trim());
