c# - 如何使用c#将文本从一个Word文档复制到另一个Word文档

Question

我想动态复制一个word文档到另一个word文档。这个过程可以在 Button Click 中完成。文档(docs)包含文本，我想将其复制到文档(docs2)

public void ReadMsWord()
    {
        string filePath = null;
        OpenFileDialog file = new OpenFileDialog();
        file.Title = "Word File";
        file.InitialDirectory = "c:\\";
        file.RestoreDirectory = true;
        if (file.ShowDialog() == DialogResult.OK)
        {
            filePath = file.FileName.ToString();
        }
        try
        {
            //Microsoft.Office.Interop.Word.Application Oword = new Microsoft.Office.Interop.Word.Application();
            //Oword.Visible = true;
            var templatepath = filePath;
            var wordapp = new Microsoft.Office.Interop.Word.Application();
            var orgnldoc = wordapp.Documents.Open(templatepath);
            orgnldoc.ActiveWindow.Selection.WholeStory();
            orgnldoc.ActiveWindow.Selection.Copy();
            var newdcmnt=new Microsoft.Office.Interop.Word.Document();
            newdcmnt.ActiveWindow.Selection.Paste();
            newdcmnt.SaveAs(@"C:\Users\Documents\TestDoc2.docx");
            System.Runtime.InteropServices.Marshal.ReleaseComObject(wordapp);
            System.Runtime.InteropServices.Marshal.ReleaseComObject(orgnldoc);
            System.Runtime.InteropServices.Marshal.ReleaseComObject(newdcmnt);
            GC.Collect();
        }
        catch (Exception ex) { MessageBox.Show(ex.ToString()); }
    }

这是我测试过的东西确保在到达 Marshal.Release 代码和 GC.Collect

之前不要停止调试器

我有 office 2010，但在您的使用部分添加以下内容

using Word = Microsoft.Office.Interop.Word;
using System.Runtime.InteropServices; 

这就是您如何实现命名空间别名

下面是代码

var fileName = "TestDoc.docx";
Object oMissing = System.Reflection.Missing.Value;
var oTemplatePath = @"C:\Documents\wrkDocuments\" + fileName;
var wordApp = new Word.Application();
var originalDoc = wordApp.Documents.Open(@oTemplatePath);

originalDoc.ActiveWindow.Selection.WholeStory();
originalDoc.ActiveWindow.Selection.Copy();

var newDocument = new Word.Document();
newDocument.ActiveWindow.Selection.Paste();
newDocument.SaveAs(@"C:\Users\Documents\wrkDocuments\TestDoc2.docx");
System.Runtime.InteropServices.Marshal.ReleaseComObject(wordApp);
System.Runtime.InteropServices.Marshal.ReleaseComObject(originalDoc);
System.Runtime.InteropServices.Marshal.ReleaseComObject(newDocument);
GC.Collect();

更改我为您创建的方法并传入适当的参数

private static void CopyWordDoc()
{
    var fileName = "TestDoc.docx";
    Object oMissing = System.Reflection.Missing.Value;
    var oTemplatePath = @"C:\Documents\wrkDocuments\" + fileName;
    var wordApp = new Word.Application();
    var originalDoc = wordApp.Documents.Open(@oTemplatePath);
    // you can do the line above by passing ReadOnly=False like this as well
    //var originalDoc = wordApp.Documents.Open(@oTemplatePath, oMissing, false);
    originalDoc.ActiveWindow.Selection.WholeStory();
    originalDoc.ActiveWindow.Selection.Copy();

    var newDocument = new Word.Document();
    newDocument.ActiveWindow.Selection.Paste();
    newDocument.SaveAs(@"C:\Documents\wrkDocuments\TestDoc2.docx");
    System.Runtime.InteropServices.Marshal.ReleaseComObject(wordApp);
    System.Runtime.InteropServices.Marshal.ReleaseComObject(originalDoc);
    System.Runtime.InteropServices.Marshal.ReleaseComObject(newDocument);
    GC.Collect();
}
