vb.net获取数组中当前位置的索引

Question

我的这个Dim transactionArray As String()()包含大量数据，两个或多个元素具有相同的值。

当我想搜索数组以找到某些内容时，我有：

  For Each tempString As String In transactionArray(tempInt1)
     If tempString.Contains(searchText) Then
        MessageBox.Show("Found It")
     End If
  Next

现在我如何获得当前指数？由于我有多个具有相同价值的元素，我猜我不能使用Array.IndexOf

Answer 1

根据你的尝试

Dim strArray As String() = {"ABC", "BCD", "CDE", "DEF", "EFG", "FGH", _
    "GHI"}
Array.IndexOf(strArray, "C")
' not found, returns -1
Array.IndexOf(strArray, "CDE")
' found, returns index

Answer 2

切换到for循环：

  For I = 0 To transactionArray(tempInt1).Count - 1
     If transactionArray(tempInt1)(I).Contains(searchText) Then
        MessageBox.Show("Found It at index " & I.ToString())
     End If
  Next
