winform怎么讀取并顯示word文檔

要在WinForm應(yīng)用程序中讀取并顯示W(wǎng)ord文檔，您可以使用Microsoft Office Interop庫。下面是一個示例代碼，演示了如何讀取Word文檔并將其內(nèi)容顯示在WinForm的TextBox控件中：

using Microsoft.Office.Interop.Word;
using System;
using System.Windows.Forms;

namespace ReadWordDocument
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void btnOpen_Click(object sender, EventArgs e)
        {
            OpenFileDialog openFileDialog = new OpenFileDialog();
            openFileDialog.Filter = "Word Documents|*.doc;*.docx";

            if (openFileDialog.ShowDialog() == DialogResult.OK)
            {
                Microsoft.Office.Interop.Word.Application wordApp = new Microsoft.Office.Interop.Word.Application();
                object missing = System.Reflection.Missing.Value;
                object filePath = openFileDialog.FileName;
                Document doc = wordApp.Documents.Open(ref filePath, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing);

                string content = "";
                foreach (Paragraph paragraph in doc.Paragraphs)
                {
                    content += paragraph.Range.Text;
                }

                txtContent.Text = content;

                doc.Close();
                wordApp.Quit();
            }
        }
    }
}

在上面的代碼示例中，首先通過OpenFileDialog控件讓用戶選擇要打開的Word文檔。然后使用Microsoft Office Interop庫中的Application和Document類打開文檔，并遍歷文檔的每個段落，將內(nèi)容讀取并顯示在TextBox控件中。

請注意，使用Microsoft Office Interop庫需要安裝相應(yīng)的Office軟件，并且在項目中添加對應(yīng)的COM引用。另外，由于Interop庫可能會導(dǎo)致一些性能問題和兼容性問題，因此建議在生產(chǎn)環(huán)境中使用更穩(wěn)定的方式來處理Word文檔，比如使用Open XML SDK或第三方庫。
