为列表框中的每个已添加项添加前缀 [英] Add Prefix for each Added item in listbox

问题描述

我有两个文本框，一个有值递增，另一个给出增量的数量，增量值显示在列表框上

i想要当值插入列表框时每个值必须有ERT 带有它的信件。



i尝试跟随，但它影响了我的系列递增



decimal j = Convert.ToDecimal（textBoxlist.Text）;



Int64 k = Convert.ToInt64（textBoxQuantity.Text）;



if（textBoxlist.Text.Length> 15）

{



for（int i = 0; i< k ; i ++）

{

SerialListBox.Items.Add（ERT+ j + i + 1）;

}



我想在每个列表框项目中添加ERT的前缀。

i have two text box one have value to increment and other one gives the amount to increment with and increment value is showen on listbox
i want when value is inserted to listbox each value must have "ERT" letters with it.

i tried following but it is effecting my incrementing of series

decimal j = Convert.ToDecimal(textBoxlist.Text);

Int64 k = Convert.ToInt64(textBoxQuantity.Text);

if (textBoxlist.Text.Length >15)
{

for (int i = 0; i < k; i++)
{
SerialListBox.Items.Add("ERT"+j + i + 1);
}

simply i want to add prefix of ERT to each list box item.

推荐答案

这是ERT+ j + i + 1 作为字符串值的母鸡你最终得到了





当J = 10且I = 0时ERT1001



来修复它改变这一行

It is taking the "ERT" + j + i + 1 as a string value hence you end up with


ERT1001 when J = 10 and I = 0

to fix it change this line

SerialListBox.Items.Add("ERT"+j + i + 1);

to

to

SerialListBox.Items.Add("ERT"+j + (i + 1));

如果我错过了你的问题，请通过解释告诉我它进一步。
