三行C#代码实现一键删除Word文档的文本框

Install-Package Spire.Doc

using Spire.Doc;

Document doc = new Document();
doc.LoadFromFile(@"C:\input.docx");  // 自动检测格式

// 删除指定索引
if (doc.TextBoxes.Count > 0)
    doc.TextBoxes.RemoveAt(0);

// 清空所有（推荐）
doc.TextBoxes.Clear();

// 遍历节处理嵌套
foreach (Section section in doc.Sections)
{
    for (int i = section.Body.ChildObjects.Count - 1; i >= 0; i--)
    {
        if (section.Body.ChildObjects[i] is Spire.Doc.Fields.TextBox)
            section.Body.ChildObjects.RemoveAt(i);
    }
}

doc.SaveToFile(@"C:\output.docx", FileFormat.Docx2016);
doc.Close();

using Spire.Doc;

class Program {
    static void Main() {
        Document doc = new Document();
        doc.LoadFromFile(@"input.docx");
        doc.TextBoxes.Clear();
        doc.SaveToFile(@"output.docx", FileFormat.Docx2016);
        doc.Close();
    }
}

string[] files = Directory.GetFiles(@"C:\docs", "*.docx");
foreach (string file in files) {
    Document doc = new Document(file);
    doc.TextBoxes.Clear();
    doc.SaveToFile(file.Replace(".docx","_clean.docx"));
    doc.Close();
}

void RemoveTextBoxes(DocumentObjectCollection objs) {
    for (int i = objs.Count - 1; i >= 0; i--) {
        if (objs[i] is Spire.Doc.Fields.TextBox) objs.RemoveAt(i);
        else if (objs[i] is ShapeGroup sg) RemoveTextBoxes(sg.ChildObjects);
