c# 在文本中查找某物或某物
c# find in text something or something
我需要在文本中搜索,但是 richtextbox.Find("something");
中是否可以有多个选项?例如richtextbox.Find("something" or "somethingelse");
你可以实现这样的东西(扩展方法 FindAny
for RichTextBox
):
public static class RichTextBoxExtensions {
public static int FindAny(this RichTextBox source, params String[] toFind) {
if (null == source)
throw new ArgumentNullException("source");
else if (null == toFind)
throw new ArgumentNullException("toFind");
int result = -1;
foreach (var item in toFind) {
if (null == item)
continue;
int v = source.Find(item);
if ((v >= 0) && ((result < 0) || (v < result)))
result = v;
}
return result;
}
}
....
int result = richtextbox.FindAny("something", "somethingelse");
