将多个值传递给Send_Mail()方法 [英] pass more than 1 values to the Send_Mail() method

问题描述

亲爱的朋友，
我有一个数据集，在其中我获得了超过1个值，例如Itemdescription及其数量，
而那个(Itemdescription，Quantity)我传递给另一个方法
Send_Mail(Itemdescription，Quantity)...但是在发送值时，我只能得到1个值，而其他值不是.
以下是代码:

Dear Friends,
i have a dataset in which i get more than 1 values like Itemdescription and its Quantity,
and that (Itemdescription,Quantity) i pass to another Method
Send_Mail(Itemdescription,Quantity)...but while sending the values i m only getting 1 value not the other''s.
following is the code:

for (int j = 0; j <= dsTotalQuantity.Tables["TotalUnitsRequired"].Rows.Count; j++)
   {
   MaterialDescpt = ds.Tables["TotalUnitsRequired"].Rows[j]["MaterialDesc"].ToString();
   TotalUnitsRequired = ds.Tables["TotalUnitsRequired"].Rows[j]["TotalUnitsRequired"].ToString();
   }

Send_Mail(MaterialDescpt,TotalUnitsRequired);

该怎么办！！！

问候，
亚米尔

推荐答案

在循环中运行类似的代码时，每次循环时都会覆盖字符串.请改用"+ ="运算符:

When you run code like that in a loop, you overwrite the string each time you loop round. Either use the "+=" operator instead:

for (int j = 0; j <= dsTotalQuantity.Tables["TotalUnitsRequired"].Rows.Count; j++)
   {
   MaterialDescpt += ds.Tables["TotalUnitsRequired"].Rows[j]["MaterialDesc"].ToString();
   TotalUnitsRequired += ds.Tables["TotalUnitsRequired"].Rows[j]["TotalUnitsRequired"].ToString();
   }

Send_Mail(MaterialDescpt,TotalUnitsRequired);

或更佳的方法是使用StringBuilder:

Or better, use a StringBuilder:

StringBuilder sbMat = new StringBuilder();
StringBuildersbTot = new StringBuilder();
for (int j = 0; j <= dsTotalQuantity.Tables["TotalUnitsRequired"].Rows.Count; j++)
   {
   sbMat.Append(ds.Tables["TotalUnitsRequired"].Rows[j]["MaterialDesc"].ToString());
   sbTot.Append(ds.Tables["TotalUnitsRequired"].Rows[j]["TotalUnitsRequired"].ToString());
   }

Send_Mail(sbMat.ToString(),sbTot.ToString());

您可能还想在其中添加一些分隔符...

You may also want to add some separator characters in there...
