无需那样复杂,根本就是动态数组.写完.NET的服务后,在Delphi里面导入WSDL后会自动生成接口.到时候直接使用就是了.给你写了一个例子.
.NET服务端:
using System;
using System.Collections;
using System.ComponentModel;
using System.Data;
using System.Diagnostics;
using System.Web;
using System.Web.Services;
namespace WebService1
{
public struct ClientData
{
public String Name;
public int ID;
}
public class WTest : System.Web.Services.WebService
{
public WTest()
{
InitializeComponent();
}
#region 组件设计器生成的代码
private IContainer components = null;
private void InitializeComponent()
{
}
/// <summary>
/// 清理所有正在使用的资源。
/// </summary>
protected override void Dispose( bool disposing )
{
if(disposing && components != null)
{
components.Dispose();
}
base.Dispose(disposing);
}
#endregion
[WebMethod(CacheDuration = 30,
Description = "返回客户记录"
]
public ClientData[] GetClientData111(int Number)
{
ClientData[] Clients = null;
if (Number > 0 && Number <= 10)
{
Clients = new ClientData[Number];
for (int i = 0; i < Number; i++)
{
Clients
.Name = "Client " + i.ToString();
Clients.ID = i;
}
}
return Clients;
}
}
}
Delphi导入WSDL生成的接口.

Delphi调用的例子:
var

R : ArrayOfClientData;
I:Integer;
begin
Intf := GetWTestSoap();
R := Intf.GetClientData111(5);
for I := Low(R) to High(R) do
ShowMessage(Format('%s ; %d',[R.Name_, R.ID]));
end;
