csv文件导出的路径选择问题。求解

[sadasdasdaasdad]

现在实现的可以把csv文件存到绝对路径下，但是想实现可以手动选择存储路径该怎么改呢？（比如点击按钮，弹出存储路径对话框，然后选择路径）

string delimiter = ",";
            string outputFilename = "Robot";
            string fullFilename = Path.Combine("D:\\11",outputFilename);//路径的选择
            StreamWriter csvStreamWriter = new StreamWriter(fullFilename, false, System.Text.Encoding.UTF8);
            //output header data
            string strHeader = "";
            for (int i = 0; i < dataGridView1.Columns.Count; i++)
            {
                strHeader += dataGridView1.Columns[i].HeaderText + delimiter;
            }
            csvStreamWriter.WriteLine(strHeader);
            //output rows data
            for (int j = 0; j < dataGridView1.Rows.Count; j++)
            {
                string strRowValue = "";

                for (int k = 0; k < dataGridView1.Columns.Count; k++)
                {
                    strRowValue += dataGridView1.Rows[j].Cells[k].Value + delimiter;

                }
                csvStreamWriter.WriteLine(strRowValue);
            }
            csvStreamWriter.Close();

这次话不多说 System.Windows.Forms.SaveFileDialog https://msdn.microsoft.com/zh-cn/library/system.windows.forms.savefiledialog(v=vs.100).aspx

Stream和StreamWriter怎么转换啊...

csvStreamWriter.BaseStream就是Stream

给你一个简单的实现方法

            var lines = dataGridView1.Rows.OfType<DataGridViewRow>().Select(r => string.Join(",", r.Cells.OfType<DataGridViewCell>().Select(c => c.Value.ToString()).ToArray())).ToList();
            lines.Insert(0, string.Join(",", dataGridView1.Columns.OfType<DataGridViewColumn>().Select(c => c.HeaderText).ToArray()));
            File.WriteAllLines(outputFilename, lines.ToArray());

这是要选中dgv中的一行吗？
