Hello Rolf，
请您使用如何定义业务对象的类，
这可以帮助我们找到一个将字符串项循环到其中的方法。
真诚的，

您好，
感谢您的回答。
如果我可以列出ObjectDataSource中的数据，我可以开发所有
其他。
您可以看到任何简单的业务对象作为数据持有者
例如
[DataObject（true）]
公共类DataObjCls01
{
string [] datas01 = new string [] {" Müller，Meyer，Schulze和Schulze。 };
public DataObjCls01（）
{
}
[DataObjectMethod （DataObjectMethodType.Select）]
public string [] GetDatas01（）
{
返回datas01;
}
}
所以我需要对自定义控件中的数据进行原始访问。
谢谢你，最诚挚的问候

Hello,
I have an ObjectDataSource which has as business-object a simple array of
strings. No problem.
I have an own (custom) control to which I give the DataSourceId and in the
custom-control so I get the ObjectDataSource. No problem
.....
ObjectDataSource src = .... //is ok i have it
Now I want
foreach(..... row .... in the list of data in src)
render the row .
but I do not know how to get the rows of data of the
ObjectDataSource-object.
Any help would be fine.
Thank you
Rolf Welskes
解决方案
Hello Rolf,
Would you please show use how you define the class for the business-object,
this may help us find a way to loop the string item in it.

Luke Zhang

Hello,
thank you for your answer.
right if I could list the data in an ObjectDataSource, I could develop all
other.
You can see any simple business-object as the holder of the data
for example
[DataObject(true)]
public class DataObjCls01
{
string[] datas01 = new string[] { "Müller", "Meyer", "Schulze" };
public DataObjCls01()
{
}
[DataObjectMethod(DataObjectMethodType.Select)]
public string[] GetDatas01()
{
return datas01;
}
}
So I need the prinzipial access to the data in a custom control.
Thank you and best regards
