推荐答案

sql作为Varbinary(Max)数据类型并将图像保存在数据库中.首先将图像保存在特定路径(而不是该图像的readallbyte)中，然后按照以下代码中的描述将这些字节保存在数据库表中:

you can save image in database of sql as Varbinary(Max) datatype and saving image in database. First save image at particular path than readallbyte from this image and save these byte in your database table as describe in this code:-

using System.IO;
using System.Data.Common;
using Microsoft.Practices.EnterpriseLibrary.Data;
using Microsoft.Practices.EnterpriseLibrary.Common;

private void saveImageFile(string FileNameWithPath)
        {
            byte[] bt = null;
            if (System.IO.File.Exists(FileNameWithPath))
            {
                bt = System.IO.File.ReadAllBytes(FileNameWithPath);
            }

            Database DbCon = "connectionString"; 
            //Get Data from Database
            DbCommand Cmd = DbCon.GetStoredProcCommand("storeProcedureName");
            DbCon.AddInParameter(Cmd, "@ImageFile", DbType.Binary, bt);
            int a=DbCon.ExecuteNonQuery(Cmd);
        }
