WebService中的DataSet序列化使用

服务端代码：

using System.Data;
using System.Linq;
using System.Web;
using System.Web.Services;

[ToolboxItem(false)]
// 若要允许使用 ASP.NET AJAX 从脚本中调用此 Web 服务，请取消对下行的注释。
// [System.Web.Script.Services.ScriptService]
public class Service1 : System.Web.Services.WebService
{
[WebMethod(Description = "获取DataSet,并进行操作")]
public bool BackUpUserTable(byte[] ds)
{
//获取用户传来的DataSet序列化 并反序列化
MemoryStream ms = new MemoryStream(ds);
BinaryFormatter bf = new BinaryFormatter();
Object o = bf.Deserialize(ms);
DataSetSurrogate dss = (DataSetSurrogate)o;
DataSet dataSet = dss.ConvertToDataSet();
//自定义操作内容
// ***
return false;
}
}
}

{
//封装DataSet
DataSet ds = new DataSet();
DataTable table = new DataTable();
table.Columns.Add("a");
table.Columns.Add("b");
table.Columns.Add("c");
for (int i = 0; i < 10; i++)
{
DataRow row = table.NewRow();
row["a"] = i.ToString() + "a";
row["b"] = i.ToString() + "b";

}
//把DataSet序列化
DataSetSurrogate dss = new DataSetSurrogate(ds);
MemoryStream ms = new MemoryStream();
BinaryFormatter bf = new BinaryFormatter();
bf.Serialize(ms, dss);
//把流装到数组里
byte[] io = ms.ToArray();
//调用WebService
ServiceReferenceUserService.Service1SoapClient userService = new WindowsClient.ServiceReferenceUserService.Service1SoapClient();

//操作
if (userService.BackUpUserTable(io))
{

}
}
