为什么txtSearch是空的？

Question

public ActionResult SearchName(string txtSearch)
{
    var model = blShoperInfo.Select().Where(p => p.Name.Contains(txtSearch));
    return PartialView(model);
}

此代码中的 txtSearch为空

Sub Nottingham3()
    For j = 1 To 17
        Dim LR As Long, i As Long
        Sheets("Stager").Cells.Clear
        With Sheets("basic list")
            On Error Resume Next
            LR = .Range("A" & Rows.Count).End(xlUp).Row
            For i = 1 To LR
                If .Range("A" & i).Value = j Then .Rows(i).Copy Destination:=Sheets("Stager").Range("A" & Rows.Count).End(xlUp).Offset(1)
            Next i
        End With
        NottsCopyData
    Next j
End Sub

我无法使用form（formMethod）因为在视图中Form方法被设置为另一个动作我现在该怎么办？两种方法是否形成尽可能的视图？
