Question

我想从My datagridview列中获取最低值！

我的datagridview的名称是 datagridview1

这是我的datagridview：

| -Number- |

| --- --- 90 |

| --- --- 70 |

| --- 20 --- |

| --- --- 80 |

| --- 50 --- |

| --- --- 60 |

我一直尝试一些代码：

Dim MinVal As Double = 99999999

For Each row As DataGridViewRow In DataGridView1.Rows

If row.Cells(0).Value < MinVal Then MinVal = row.Cells(0).Value

Next

TextBox9.Text = MinVal

没有错误。但结果是 60 20

发生了什么？请帮助我！

Answer 1

    Dim Max As Integer = 0

    For Each rws As DataGridViewRow In DataGridView1.Rows
        If Max < rws.Cells(0).Value Then Max = rws.Cells(0).Value
    Next

'Maximum Value
Msgbox(Max)

对于最小值，您必须使用该最大值

    Dim Min As Integer = Max

    For Each rws As DataGridViewRow In DataGridView1.Rows
        If Min > rws.Cells(0).Value Then Min = rws.Cells(0).Value
    Next

'Minimum Value
Msgbox(Min)

Answer 2

尝试以下代码

Private Structure cell
    Dim rowIndex As Integer
    Dim columnIndex As Integer
End Structure
    Dim cells = From r As DataGridViewRow In DataGridView1.Rows.Cast(Of DataGridViewRow)() _
                    Where Not r.IsNewRow _
                    Select CInt(r.Cells(0).Value)

        Dim min As Integer = cells.Min
Dim minval As New cell With {.columnIndex = 0, .rowIndex = Array.IndexOf(cells.ToArray, min)}

最大值---

 Dim max As Integer = cells.Max
    Dim maxAddress As New cell With {.columnIndex = 0, .rowIndex = Array.IndexOf(cells.ToArray, max)}
