Question

我使用以下代码将所选行从DatagGridview导出到Word文档。代码正在运行，但有一个问题。它首先导出最后一行，我无法找到使其按顺序导出的方法。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)

我认为这个Linq应该有用（你需要{＆＃34}位于＆＃34; .cs＆＃34;文件的顶部。）：

using System.Linq;

[编辑] OP要求的更多信息：

这是使用Linq按照每行索引的顺序对返回的行进行排序。

See this documentation for an introduction to Linq

但简单地说，它的工作方式是这样的：

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

为了按照正确的顺序排列它们，我们需要按每行var orderedRows = from DataGridViewRow row in dataGridView1.SelectedRows orderby row.Index select row; foreach (DataGridViewRow row in orderedRows) ...属性对它们进行排序。

上面的Linq说：

＆＃34;获取dataGridView1.SelectedRows中的所有行，并按每行的Index属性对它们进行排序，然后按顺序返回所有行＆＃34;。

但这太复杂了，无法完全进入这里;你必须阅读我发布的Linq简介！
