解决导入中文SQL数据乱码问题

解决导入中文SQL数据乱码问题

我的第一篇博文

小弟是做.net的 ，菜鸟一名

开发环境vs2008+sql 2005

问题重现：通过ADO.NET 导入txt文件到数据库指定表格，中文数据全部变成乱码：����ʡ��ͨ��

private void button1_Click(object sender, EventArgs e)
        {
            if (openFileDialog1.ShowDialog() == DialogResult.OK)//如果选中文件
            {
                using (FileStream filestreams = File.OpenRead(openFileDialog1.FileName))//获得导入文件的文件名
                {
                    using (StreamReader streamereader = new StreamReader(filestreams))
                    {//使用 StreamReader 读取标准文本文件的各行信息,  Encoding.GetEncoding("gb2312")的编码方式防止汉字乱码
                        string line = null;
                        while ((line = streamereader.ReadLine()) != null)
                        {//如果读入数据不为空
                            string[] strs = line.Split(',');
                            string  id = strs[0];
                            string name = strs[1];
                            string sex = strs[2];
                            string sfz = strs[3];
                            string birth = strs[4];
                            string syd = strs[5];
                            using (SqlConnection conn = new SqlConnection("server=.;database=DB1;Integrated security=true"))
                            {
                                conn.Open();
                                using (SqlCommand cmd = conn.CreateCommand())
                                {
                                    cmd.CommandText = "insert into Student(学号,姓名,性别,身份证号,生日,生源地) values(@Id,@Name,@Sex,@Sfz,@Birth,@Syd);";
                                    cmd.Parameters.Add(new SqlParameter("Id",id));
                                    cmd.Parameters.Add(new SqlParameter("Name",name));
                                    cmd.Parameters.Add(new SqlParameter("Sex", sex));
                                    cmd.Parameters.Add(new SqlParameter("Sfz", sfz));
                                    cmd.Parameters.Add(new SqlParameter("Birth", birth));
                                    cmd.Parameters.Add(new SqlParameter("Syd", syd));
                                    cmd.ExecuteNonQuery();

                                }
                            }
                        }
                    }
                }
                MessageBox.Show("c");
            }
        }
    }

 

解决方法：查了各种解决办法

最后没想到 简单的让人吐血：字符编码问题，只需把 

 using (FileStream filestreams = File.OpenRead(openFileDialog1.FileName))//获得导入文件

增加为

using (StreamReader streamereader = new StreamReader(filestreams,Encoding.GetEncoding("gb2312")))
