[U8开发] com对象调用类 DxComObject

避免复杂的com引用

 1 using System;

调用1- 登录

 1          DxComObject dxComObject = new DxComObject("U8Login.clsLogin");
 2         array = new object[1]
 3         {
 4             LoginString
 5         };
 6         if (!(bool)dxComObject.DoMethod("ConstructLogin", array))
 7         {
 8             throw new Exception("U8登录信息错误！");
 9         }
10 
11          array = new object[8]
12         {
13             "ST",
14             errMsg,
15             errMsg,
16             errMsg,
17             errMsg,
18             errMsg,
19             errMsg,
20             errMsg
21         };
22         if (!(bool)dxComObject.DoMethod("Login", array))
23         {
24             throw new Exception(string.Format("登录{0}错误！{1}", "ST", dxComObject["ShareString"].ToString()));
25         }
26 
27          string text = dxComObject["UfDbName"].ToString();
28         string DBUser = string.Empty;
29         string DBPassword = string.Empty;
30         string text2 = SplitDBInfo(text, out DBUser, out DBPassword);

调用2- CO调用

DxComObject dxComObject2 = new DxComObject("USERPCO.VoucherCO");
array = new object[2]
{
dxComObject.ComInstance,
 errMsg
 };
 if (!(bool)dxComObject2.DoMethod("IniLogin", array))
{
 throw new Exception("初始化CO接口失败！" + array.GetValue(1).ToString());
}

...

            if (!(bool)dxComObject2.DoMethod("Insert", array, paramMods))
            {
                throw new Exception("单据保存失败！" + array.GetValue(4).ToString());
            }
            empty = array.GetValue(6).ToString();
            errMsg = "入库单保存成功！";
