推荐答案

.WriteLine(ComStr1.PadRight(15, ""c) & _
  Space(2) & _
 ControlChars.Tab & ComStr2.PadLeft(3," "c) & _
 Space(4) & _
 ControlChars.Tab & ComStr3.ToString.PadLeft(4," "c) & _
 Space(3) & _
 ControlChars.Tab & ComStr11.ToString.PadLeft(5, " "c))




//Comstr1=Description
//ComStr2=Qty
//Comstr3=Rate
//Comstr11=Amount
