WebApi删除单据的问题

用管理员进去后查看WebApi的调用例子，现在通过该例子删除一个银行信息，没有提示错误，但是也没有删除，请问是怎么回事？
ApiClient _apiClient = new ApiClient("http://192.168.98.5/k3cloud/");
string _strDBID = "54852e978bca6d";
string _strUserName = "001176";
string _strPassword = "888888";
object[] _objInfor = new object[] {_strDBID,_strUserName,_strPassword,2052};

var ret = _apiClient.Execute("Kingdee.BOS.WebApi.ServicesStub.AuthService.ValidateUser", _objInfor);
var result = JObject.Parse(ret)["LoginResultType"].Value();
if (result ==1)
{
_apiClient.Execute("Kingdee.BOS.WebApi.ServicesStub.DynamicFormService.Delete", new object[] { "BD_BANK", "{\"FCreateOrgId\":103,\"FNumber\":[\"00001\"]}" });

// _apiClient.Execute("Kingdee.BOS.WebApi.ServicesStub.DynamicFormService.Delete", new object[] { "BD_BANK", "{\"CreateOrgId\":103,\"Numbers\":[\"00001\"]}" });该成这样也是不行
}

麻烦大神帮忙解答一下，谢谢！
