问题描述

有人可以告诉我如何将word,pdf,excell等文件上传到SQL Server 2005以及如何检索它们.

Can anybody tell me how to upload word, pdf, excell etc file to SQL server 2005 and how to retrieve them.

推荐答案

将它们读取为数组字节:
Read them as an array of bytes:
byte[] bytes = File.ReadAllBytes(@"D:\Temp\MyFile.doc");


然后将它们插入表中:


Then insert them into your table:

using (SqlConnection con = new SqlConnection(strConnect))
    {
    con.Open();
    using (SqlCommand com = new SqlCommand("INSERT INTO myTable (myFileDataColumn) VALUES (@DATA)", con))
        {
        com.Parameters.AddWithValue("@DATA", bytes);
        com.ExecuteNonQuery();
        }
    }

将它们读回非常相似:

To read them back is very, very similar:

using (SqlConnection con = new SqlConnection(strConnect))
    {
    con.Open();
    using (SqlCommand com = new SqlCommand("SELECT myFileDataColumn FROM myTable", con))
        {
        using (SqlDataReader reader = com.ExecuteReader())
            {
            while (reader.Read())
                {
                byte[] bytes = (byte() reader["myFileDataColumn "];
                File.WriteAllBytes(@"D:\Temp\MyFileBackAgain.doc", bytes);
                }
            }
        }
    }
