在VB.Net中的数据表中查找包含行和列号的字符串

Dim targetString As String = "目标字符串"
Dim foundRows As New List(Of Integer)()
Dim foundColumns As New List(Of Integer)()

For rowIndex As Integer = 0 To dataTable.Rows.Count - 1
    For columnIndex As Integer = 0 To dataTable.Columns.Count - 1
        Dim cellValue As String = dataTable.Rows(rowIndex)(columnIndex).ToString()
        If cellValue.Contains(targetString) Then
            foundRows.Add(rowIndex)
            foundColumns.Add(columnIndex)
        End If
    Next
Next

' 输出找到的行和列号
For i As Integer = 0 To foundRows.Count - 1
    Console.WriteLine("找到目标字符串的位置：行号 = {0}，列号 = {1}", foundRows(i), foundColumns(i))
Next
