本文介绍如何使用VSTO和C#在Word文档及其文本框中实现查找和替换文本的功能。通过利用StoryRanges和Range等类，可以有效地定位到文档中的指定文本并进行替换。

主要参考StoryRanges，NextStoryRange，WdStoryType，Range这几个类。

Replace text in Word textbox objects using VSTO and C#

/// <summary>
/// 查找并替换文本
/// </summary>
/// <param name="wordApp"></param>
/// <param name="oldStr"></param>
/// <param name="newStr"></param>
public void SearchReplace(string oldStr, string newStr)
{
	#region 文字区域
	object replaceAll = WdReplace.wdReplaceAll;

	wordApp.Selection.Find.ClearFormatting();
	wordApp.Selection.Find.Text = oldStr;

	wordApp.Selection.Find.Replacement.ClearFormatting();
	wordApp.Selection.Find.Replacement.Text = newStr;

	wordApp.Selection.Find.Execute(
		ref missing, ref missing, ref missing, ref missing, ref missing,
		ref missing, ref missing, ref missing, ref missing, ref missing,
		ref replaceAll, ref missing, ref missing, ref missing, ref missing);
	#endregion

	#region 文本框
	StoryRanges sr = wordDoc.StoryRanges;
	foreach (Range r in sr)
	{
		Range r1 = r;
		if (WdStoryType.wdTextFrameStory == r.StoryType)
		{
			do
			{
				r1.Find.ClearFormatting();
				r1.Find.Text = oldStr;

				r1.Find.Replacement.ClearFormatting();
				r1.Find.Replacement.Text = newStr;

				r1.Find.Execute(
					ref missing, ref missing, ref missing, ref missing, ref missing,
					ref missing, ref missing, ref missing, ref missing, ref missing,
					ref replaceAll, ref missing, ref missing, ref missing, ref missing);

				r1 = r1.NextStoryRange;
			} while (r1 != null);
		}
	}
	#endregion
}
