请问upload一讲中，照片上传的个数能否限制，不限制张数，哪怕就是压缩了文件也比较多，能不能限制比如一次最多选6张，看了视频的讲解，没有提到这个问题

Case "upload.htm"
        Dim wb As New weui
        wb.AddForm("","form1","receive.htm")
        With wb.AddInputGroup("form1","ipg1","文件上传")
            With .AddUploader("up128","照片",True)
                .AllowDelete = True '允许删除
                .Incremental = True '允许重复选择文件或连续拍照
                .ScaleWidth = 400 '自动压缩图片宽度为400个像素,高度等比例压缩
            End With
        End With
        With wb.AddButtonGroup("form1","btg1",True)
            .Add("btn1", "确定", "button").Attribute= "" '调用js函数上传
        End With
        wb.AddToast("","tst1", "正在上传",1)
        wb.AddToast("","tst2", "上传成功",0)
        wb.AddToast("","tst3", "上传失败",0).Icon= "warn"
        wb.AppendHTML("<script src='./lib/ajaxform.js'></script>") '引入脚本文件
        e.WriteString(wb.Build) '生成网页
    Case "receive.htm"
        For Each key As String In e.Files.Keys
            For Each fln As String In e.Files(key)
                e.SaveFile(key,fln,"d:\web\uploadfiles\" & fln) '保存接收到的文件
            Next
        Next
        e.WriteString("OK")

代码加入后照片能正常接收，表格中记录会同步。但弹出上传失败的红色标志。请问蓝蓝老师，这是什么问题呢？

Case "receive.htm"

For Each key As String In e.Files.Keys

If e.Files(key).count > 6 Then

e.WriteString("照片不能多于6张!!")

Return

Else

Dim nms() As String = {"内容"}

Dim drc As DataRow = DataTables("表A").AddNew()

For Each nm As String In nms

drc(nm) = e.PostValues(nm)

If key = "up1" Then

Dim lst As List(of String) = drc.Lines("照片")

For Each fln As String In e.Files(key)

Dim n As String = Format(Date.Now,"yyyyMMddHHmmssffff") & fln

e.SaveFile(key,fln,"C:\web\uploadfiles\" & n)

lst.Add(n)

drc.Lines("照片") = lst

drc.save()

End If

e.WriteString("ok")

function submitForm(){

show("tst1",2000);

var result = submitAjaxForm('form1','afterSubmit');

}

function afterSubmit(result){

hide("tst1");

if (result=='OK') {

show("tst2");

location="upload.htm";

}

else{

show("tst3",2000);

}
