从保存在SQL Server数据库中的二进制文件中检索C＃对象

Question

我想要保存并从数据库中检索对象。我编写C＃代码来保存它，如下所示，它工作正常。现在我可以将对象保存到数据库中。

ReportObject ro = new ReportObject()
{
    Name = ctrl.Name,
    BackColor = ctrl.BackColor,
    ForeColor = ctrl.BackColor,
    Fonts = ctrl.Font,
    TypeofControl = ctrl.GetType()
};

MemoryStream memStream = new MemoryStream();
StreamWriter sw = new StreamWriter(memStream);

sw.Write(ro);

string sql = "INSERT INTO [TemplateDetails] ([Object]) VALUES (@Object)";

SqlCommand cmd = new SqlCommand(sql, con, tran);
cmd.Parameters.Add("@Object", SqlDbType.VarBinary, Int32.MaxValue);
cmd.Parameters["@Object"].Value = memStream.GetBuffer();

cmd.ExecuteNonQuery();

我已经在SQL Server数据库中保存了一个C＃对象ReportObject。我想将其检索回C＃对象。

string sql = "SELECT [Object] FROM [TemplateDetails]"

SqlDataReader dr = db.Reader(sql);

if (dr.Read())
{
byte[] arrays = (byte[])dr["Object"];
}
