我有一支程式, 需从DataGridView中将数据导出至csv格式的文件的,在本地没有问题, 但是放到其他的电脑上,就会出现乱码, 是什么原因?

代码如下:
using System;
using System.Collections.Generic;
using System.Text;
using System.Windows.Forms;
using

namespace Statistic.BaseClass
{
    class DataExport
    {
        public static void ExportToCSV(DataGridView dgv, string fileName)
        {
            if (dgv.Rows.Count < 1)
            {
                MessageBox.Show("没有记录！", "提示", MessageBoxButtons.OK, MessageBoxIcon.Information);
                return;
            }
            string strFileName = Application.StartupPath + "\\" + fileName;
            StreamWriter sw = new StreamWriter(strFileName, false, Encoding.UTF8);
            string strLine = "";
            foreach (DataGridViewColumn col in dgv.Columns)
            {
                if (col.Visible)
                {
                    strLine += col.HeaderText.Trim() + ",";
                }
            }
            strLine = strLine.Substring(0, strLine.Length - 1);
            sw.WriteLine(strLine);
            sw.Flush();

            foreach (DataGridViewRow dgvr in dgv.Rows)
            {
                strLine = "";
                foreach (DataGridViewCell dgvc in dgvr.Cells)
                {
                    if (dgvc.Visible)
                    {
                        if (dgvc.Value == null)
                        {
                            strLine += " ,";
                        }
                        else
                        {
                            strLine += dgvc.Value.ToString().Trim() + ",";
                        }
                    }
                }
                sw.WriteLine(strLine);
                sw.Flush();
            }
            sw.Close();
            MessageBox.Show(string.Format("数据已成功导出至\n{0}\n文件中!", strFileName), "导出成功", MessageBoxButtons.OK, MessageBoxIcon.Information);
        }
    }
}

问题已解决, 具体代码如下:

using System;
using System.Collections.Generic;
using System.Text;
using System.Windows.Forms;
using

namespace Statistic.BaseClass
{
    class DataExport
    {
        public static void ExportToCSV(DataGridView dgv, string fileName)
        {
            if (dgv.Rows.Count < 1)
            {
                MessageBox.Show("没有记录！", "提示", MessageBoxButtons.OK, MessageBoxIcon.Information);
                return;
            }

            SaveFileDialog sfDialog = new SaveFileDialog();
            sfDialog.Filter = "CSV文件(*.csv)|*.csv|文本文件(*.txt)|*.txt|所有文件(*.*)|*.*";
            sfDialog.FilterIndex = 0;
            sfDialog.FileName = fileName;
            if (sfDialog.ShowDialog() == DialogResult.OK)
            {

                string strFileName = sfDialog.FileName;
                StreamWriter sw = new StreamWriter(strFileName, false, Encoding.Unicode);
                string strLine = "";
                foreach (DataGridViewColumn col in dgv.Columns)
                {
                    if (col.Visible)
                    {
                        strLine += "\"" + col.HeaderText.Trim().Replace("\"", "\\\"") + "\"" + "\t";
                    }
                }
                strLine = strLine.Substring(0, strLine.Length - 1);
                sw.WriteLine(strLine);
                sw.Flush();

                foreach (DataGridViewRow dgvr in dgv.Rows)
                {
                    strLine = "";
                    foreach (DataGridViewCell dgvc in dgvr.Cells)
                    {
                        if (dgvc.Visible)
                        {
                            if (dgvc.Value == null)
                            {
                                strLine += "\t";
                            }
                            else
                            {
                                strLine += "\"" + dgvc.Value.ToString().Trim().Replace("\"","\"\"") + "\"" + "\t";
                            }
                        }
                    }
                    sw.WriteLine(strLine);
                    sw.Flush();
                }
                sw.Close();
                MessageBox.Show(string.Format("数据已成功导出至\n{0}\n文件中!", strFileName), "导出成功", MessageBoxButtons.OK, MessageBoxIcon.Information);
            }
        }
    }
}
