构建了一个数据表，需要将数据表第一行转换成字符串，请问该怎么写vb代码？谢谢。
BuildDataTable activity.
And you need to convert only the first row to string ?
I 'm unclear of your question
You need to convert the column datatype or you need to change the row
If possible can tell more about your task so that it will be easily understandable

Yes, I need to convert the first row of the datatable. This datatable may have only one row or more rows. I know the output activity can convert the whole datatable to string. But I hope to extract the first line.
Okay @Marginalizer
Use this expression in output datatable
DT1.AsEnumerable().take(1).CopyToDataTable this will get you the first row values with the headers
If you want to get separately use for each row in datatable and pass the dt
- Assign SameVariable=Current(“ColumnName”).tostring using this you can get all the row values

Thank you @Sudharsan_Ka
But how can I get the header only?
Okay after getting that string value use this expression
System.Text.RegularExpressions.Regex.Match(yourString,“.*(?=\n)”).ToString
Hope this helps
