我正在使用以下代码将选定的行从DatagGridviewWord 文档导出。代码正在运行,但存在一个问题。它首先导出最后一行,我想不出一种方法让它按顺序导出。例如,如果我选择行 [0,1,2,3],它将导出行 [3] 而不是 [2] 和 [1]。任何想法问题是什么?

public void WordDoc(string getfilename)
        {



            object FileName = getfilename;


            //Create word Application Object
            Word.Application word = new Word.Application();

            //Create word document Object
            Word.Document doc = null;

            //Create word Missing Object
            object missing = System.Type.Missing;

            object readOnly = false;
            object isVisible = false;
            // make visible Word application
            word.Visible = true;

            try
            {
                doc = word.Documents.Open(ref FileName, 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);
                doc.Activate();    
foreach (DataGridViewRow rows in dataGridView1.SelectedRows)
                        {
                        string item1 = rows.Cells[0].Value.ToString();
                                string item2 = rows.Cells[2].Value.ToString();
                                string item3 = rows.Cells[3].Value.ToString();
                                string item4 = rows.Cells[4].Value.ToString();
                                string item5 = rows.Cells[5].Value.ToString();
                                string item6 = rows.Cells[6].Value.ToString();
                                string item7 = rows.Cells[7].Value.ToString();
                                string item8 = rows.Cells[8].Value.ToString();
                                string item9 = rows.Cells[9].Value.ToString();
                                string item10 = rows.Cells[10].Value.ToString();
                                string item11 = rows.Cells[11].Value.ToString();
                                string item12 = rows.Cells[12].Value.ToString();

                                this.FindAndReplace(word, "!0!", item1);
                                this.FindAndReplace(word, "!1!", item2);
                                this.FindAndReplace(word, "!2!", item3);
                                this.FindAndReplace(word, "!3!", item4);

                MessageBox.Show("Error : " + ex.Message);
            }
        }



            private void FindAndReplace(Word.Application word, object findText, object replaceText)
            {
                word.Selection.Find.ClearFormatting();

我认为这个 Linq 应该可以工作(你需要using System.Linq;在“.cs”文件的顶部。):

var orderedRows = from DataGridViewRow row in dataGridView1.SelectedRows
                  orderby row.Index
                  select row;

foreach (DataGridViewRow row in orderedRows)
    ...

[编辑] OP 要求的更多信息:

这是使用 Linq 按每行索引的顺序对返回的行进行排序。

有关 Linq 的介绍,请参阅此文档

但简而言之,它的工作原理是这样的:

首先,意识到 DataGridView.SelectedRows 按用户选择的顺序返回行。

为了让它们按正确的顺序排列,我们需要按每一行的.Index属性对它们进行排序。

上面的 Linq 通过说:

“获取 dataGridView1.SelectedRows 中的所有行并按每行的 Index 属性对它们进行排序,然后按该顺序返回所有行”。

但是在这里完全进入太复杂了;您必须阅读我发布的 Linq 简介!
