各位专家好!

写了个函数，但是调来调去都说语法错误？ 请各位帮忙看看是怎么回事？

Dim bomid As String = args(0) \'物料清单编码
Dim part As String = args(1) \'主料物料编号
Dim diffqty As Double = args(2) \'主物料编号不足数
Dim poqty As Double  \'在途数量

Dim level As Integer \'优先级
Dim drs As List(of DataRow) = DataTables("物料代用明细").Select(" 物料清单编码 = \'" & bomid & "\' And 原物料编号 = \'" & part & "\'")
If drs IsNot Nothing Then \'如果有代用料的话
    For level = 0 To drs.Count
        Dim dr As DataRow = DataTables("物料代用明细").Find("物料清单编码 = \'" & bomid & "\' And 原物料编号 = \'" & part & "\' And 优先级 = \'" & level & "\'")
        \'If dr IsNot Nothing Then  \'如果代用料找到的话,优先级为0开始查找
            Dim Total_stock As Double = Functions.Execute("GetTotalStock",dr("代用物料编号")) \'先查找其总库存
            If Total_stock >= (-diffqty) Then \'如果代用料库存大于或等于不足数时,看是否存在需求表,存在则提取不足数,看是不是能够满足,能则更新,不能则下一个,不存在则写入需求表
                Dim dr1 As DataRow = DataTables("物料需求表").Find("物料编号 = \'" & dr("代用物料编号") & "\'")
                If dr1 IsNot Nothing Then \'是否存在在物料需求表,存在则提取不足数,不存在则新增一个
                    Dim Sub_qty As Double = dr1("不足数量")
                    If Sub_qty >= (-diffqty) Then \'存在在物料需求表里的代用料的不足数大于或等于主料不足数,则选其代用.否则找下一个.
                        dr1("需求数量") = dr1("需求数量") - diffqty
                        dr1("不足数量") = dr1("不足数量") - diffqty
                        dr1("备注")=dr1("备注") & "/" & "代用" & part & ":" &(-diffqty)
                        Exit For
                    Else
                        level = level + 1 \'选择下一个优先级的代用料
                    End If
                Else \'新增一条记录在物料需求表中
                    poqty =0
                    For Each dr3 As DataRow In DataTables("仓库主文件").DataRows \'b
                        Dim dr4 As DataRow = DataTables("库存清单主文件").Find("物料编号 = \'" & dr("代用物料编号") & "\'And 仓库编码 = \'" & dr3("仓库编码") & "\'")
                        If dr4 IsNot Nothing Then \'提取库存的在途数量和总库存量
                            poqty = poqty + dr3("在途数量") \'总在途数量
                        End If
                    Next \'b
                   
                    Dim dr2 As DataRow = DataTables("物料需求表").AddNew
                    dr2("物料编号") = dr("代用物料编号")
                    dr2("描述") = dr("物料描述")
                    dr2("单位") = dr("单位")
                    dr2("需求数量") = (-diffqty)
                    dr2("在途数量") = poqty
                    dr2("不足数量") = Total_stock + poqty - dr2("需求数量")
                    dr2("备注") = "代用" & part & ":" & dr2("需求数量")
                    Functions.Execute("Write_Stock_ToMrp",dr("代用物料编号"),dr2)
                    Exit For
                End If
            End If
      \'End If              .
    Next
End If
Return Nothing

把高亮处代码取消注释后出现错误。

从图片上看，你没有把IF注释掉。。

错误提示表明，你少了end if ，说明你多了个IF

\'End If              .

麻痹啦，太麻痹啦！最后那个小红点，看见没？

看到了，果然是这样。多谢！看来得清洁一下显示屏。
