こんにちは。UiPath Studio Enterprise Editionを1週間後から使う予定のある初心者です。まだUiPathはインストールしていません。
String変数から空文字を削除する方法は下記を連続実行する方法があると認識しておりますが、1行で半角スペースと全角スペースを削除する構文はないでしょうか。
This above LINQ query iterates through each row and each column of the DataTable, replacing any empty or whitespace-only values with an empty string.
For DataRow:
For Each column In YourDataRow.Table.Columns
Assign activity-> YourDataRow(column) = If(IsDBNull(YourDataRow(column)) OrElse String.IsNullOrWhiteSpace(YourDataRow(column).ToString()), String.Empty, YourDataRow(column).ToString())
Next
May be you could try this Invoke code too For DataTable:
Dim dataTable As DataTable = YourDataTable
For Each row As DataRow In dataTable.Rows
For Each column As DataColumn In dataTable.Columns
row(column) = If(IsDBNull(row(column)) OrElse String.IsNullOrWhiteSpace(row(column).ToString()), String.Empty, row(column).ToString())
Next
Next
Make sure to replace YourDataTable with the actual name of your DataTable variable. This code iterates through each row and each column of the DataTable, replacing any empty or whitespace-only values with an empty string.
For DataRow:
Dim dataRow As DataRow = YourDataRow
For Each column As DataColumn In dataRow.Table.Columns
dataRow(column) = If(IsDBNull(dataRow(column)) OrElse String.IsNullOrWhiteSpace(dataRow(column).ToString()), String.Empty, dataRow(column).ToString())
Next
Replace YourDataRow with the actual DataRow variable in your workflow.
ありがとうございます。WFを実行したら、作成いただいたアクティビティのところで、
Execption has been thrown by the target of an invocationというエラーが出ます。dtにデータが存在することはローカル出力で確認済みです。
原因分かりますでしょうか?
まさかReplaceを3連結したのは無関係ですよね?
