c＃中的数据网格视图 [英] Datagrid view in c#
问题描述
嗨我正在编写一个代码，其中我从文本框中的串口获取数据。现在我希望数据在datagrid中。输出如下：
------------------------------ JL206F ID：VDE40050
2015/05/29 11:02:19
JBatch_No.:067
JOperator ID：15
-------------------- ------------
混合计数
W --- -----------------------------存款金额：0.00
- -------------------------------
denom count value
UVK（| ???? DW50D 1 50.00
JUVK（| ???? DW20D 1 20.00
JUVK（| ???? DW10ND 1 10.00
J ----- ---------------------------
总计：3 80.00
--------------------------------
硬币：0.00
-------------------- ------------
余额：0.00
我希望我的网格看起来像这样
名称ID日期时间Batch_No运营商ID存款金额denom
计算总金币余额
和我的当我分割数据时，代码如下，它给出了spli [1]数组超出范围的错误。我怎么能这样做我是c＃的新手。这是我的代码
hi I am writing a code in which i got a data from serial port in a textbox. Now I want that data to be in datagrid. The output is as follows:
------------------------------JL206F ID:VDE40050
2015/05/29 11:02:19
JBatch_No.:067
JOperator ID:15
--------------------------------
Mixed Counting
W--------------------------------Deposit Amount: 0.00
--------------------------------
denom count value
UVK(|????DW50D 1 50.00
JUVK(|????DW20D 1 20.00
JUVK(|????DW10ND 1 10.00
J--------------------------------
Total: 3 80.00
--------------------------------
Coin: 0.00
--------------------------------
Balance: 0.00
I want my grid to look like this
Name ID Date Time Batch_No Operator ID Deposit amount denom
Count value total coin balance
and my code is as follows when i am splitting data it is giving me error on spli[1] array out of bound. How Can I do it I am new to c#. Here is my code

推荐答案
您正在尝试将字符串与相同的分隔符分开两次！
首先 str 分隔为行：
You are trying to separate your string with the same separators twice!
First str is separated to the lines:
string[] stringSeparators = new string[] { "\n\n\r" };
string[] lines = str.Split(stringSeparators,StringSplitOptions.None );
...然后你再次尝试将行的项目分开：
...then you try to separate the items of lines again:
foreach (var line in lines)
{
string[] split = line.Split(stringSeparators,StringSplitOptions.None);
...
这是矛盾的，因为在第一次拆分中删除了分隔符。您应该为第二次分离选择不同的分隔符。
this is contradiction, because the separator characters are removed in the first split. You should choose different separator for the second separation.
