DataRow変数drを配列に変換したい。

2.相談したいこと

dr.ItemArray
でも
dr.ToArray
でもどちらでも行けますか？それとも、dr.ToArrayは、dr.ItemArrayで配列化後、さらに加工した結果を配列に入れる場合に使う？

@gorby,

If you are looking for converting DataRow to Array, use this code in Assign activity.

varArray =Dr.ToArray();

Thanks,

Hi @gorby

Using ItemArray:

• dr.ItemArray returns an array containing all the values in the DataRow. This is useful when you simply want to extract all the values from the DataRow into an array without any additional processing.
• Using ToArray:

dr.ToArray() is not directly available in UiPath as a method for DataRow. Typically, ToArray() is a method used with collections like List or Enumerable. If you want to further process the DataRow and then convert the result into an array, you might first convert the DataRow to an IEnumerable and then use ToArray().

For example, if you filter or process the DataRow in some way, you might use LINQ and then convert the result to an array

dr.ItemArray.Where(Function(x) x IsNot Nothing).ToArray()

1. Here, ItemArray is used to get the array, and then LINQ operations are applied before converting the final result into an array.

In summary, dr.ItemArray is the straightforward way to convert a DataRow to an array. If you need further processing, you can apply LINQ or other methods and then convert the result to an array using ToArray().
