WebService应该是一个基于Http,Soap的协议栈。底层还是依赖着Http协议(一般来说)。
可以把对象经过XML序列化之后或者是服务A上的XML读进String里，然后返回。这样调用
再把String里的XML反序列化或者读成XML文件就可以了。（当然方法很多)
如果都是.Net调用，而且是一个solution里的工程（两个WebService)那么返回自定义
对象也是可以的。
//WebMethodCollection.asmx.cs
//Method 1: Parameter is a complex type.
[WebMethod]
public string DisplayPersonInfo(ClsCommon.Person someone)
{
return someone.Name + " " + someone.Gender;

//Method 2: Return a ArrayList.
[WebMethod]
public ArrayList GetPersonList(int number)
{
ArrayList personList = new ArrayList(number);
for(int i=0; i<number; i++)
{
ClsCommon.Person someone = new ClsCommon.Person();
//Just for test.
someone.Name = "Person" + i.ToString();
someone.Gender = "Male";
personList.Add(someone);
}
return personList;
}
//Method 3: Return a complex type.
[WebMethod]
public ClsCommon.Person GetPersonInstance( string strName, string strGender )
{
ClsCommon.Person someone = new ClsCommon.Person(strName, strGender);
return someone;
}
//Method 4: string ( xml serialization )
[WebMethod]
public string GetSerializedPerson()
{
ClsCommon.Person Jordan = new ClsCommon.Person("Jordan", "Male");
//Serialized the person instance. Return the xml string.
return ClsCommon.SerializeController.XmlSerialize(Jordan);
}
//Method 5: byte[] ( Binary serialization )
[WebMethod]
public byte[] GetBinarySerializedPerson()
{
ClsCommon.Person YaoMing = new ClsCommon.Person("YaoMing", "Male");
//Serialized the person instance. Return the byte array.
return ClsCommon.SerializeController.BinarySerialize(YaoMing);
}
//Method 6: Get the byte array of the excel file.
[WebMethod]
public byte[] GetByteArrayOfExcel()
{
//Just for test
string fileName = "D:\\tmp\\TestExcel\\test.xls";
byte[] bytesData;
using(FileStream fs = File.OpenRead(fileName))
{
bytesData = new byte[(int)fs.Length];
fs.Read(bytesData, 0, bytesData.Length);
fs.Close();
}
return bytesData;
