Txt文件问题C＃ [英] Txt File Problem C#
问题描述
整天都在努力，无法找到解决方案
for（int i = 0; i< NumberOfLines; i ++）
{
ID [i] = tr.ReadLine（）;
lines = ID [i] .Split（new Char [] {''''}};
comboBox1.Items.Add（lines [0]）;
}
private void comboBox1_SelectedIndexChanged（object sender，EventArgs e）
{
textBox1.Text = lines [1];
}
ok问题仅为行[1]读取数组的结尾，我总是得到最后的结果无论我怎么做尝试改变它，但行[0]工作正常???我怎么能让文本框只显示基于行[0]的正确的东西。
示例行[0] = 1
我怎样才能获得行[ 1]显示第一行。
行[0] = 2
我怎样才能得到行[1]来显示第二行等等。
或者至少告诉我怎么做这个
string [，] threebythree = new string [Int16.Parse（ID [i]），Int16.Parse（lines [i]）];
因为即使我得到了转换
错误：输入字符串的格式不正确。
不完全确定这里的目标是什么......但看起来如果你从列表框中选择第二项（迭代1，因为它是零索引）你想要第二行您的文件出现在文本框中。列表框中选择的第四个项目=文本框中的第四个项目。这是目标吗？
两者都是零索引的。所以从列表框中取出.SelectedIndex值并将其作为行号索引显示在文本框中。
如果我误解了你的目标并导致你走入歧途，我的最深的道歉。
sry我以一种令人困惑的方式说出来。
文本文件中有这个：
0 string1 5
1 string2 10
2 string3 15
行[0]为0,1,2
行[1]为string1，string2，string3
行[2]为5,10,15
ID [0]是0 string1 5
ID [1]是1 string2 10
ID [2}是2 string3 15
当我尝试将行[1]写入textbox1.text即可获得string3。
i不知道使其成为string1的代码然后是string2，然后是string3。
所以它的阅读最后一个数组。
i想让一个像（ID [i]，lines [i]）这样的数组成为可能，这就是我在回复中尝试做的，但当然不行
been working on this all day and cant figure out a solution
for (int i = 0; i < NumberOfLines; i++)
{
ID[i] = tr.ReadLine();
lines = ID[i].Split(new Char[] { '' '' });
comboBox1.Items.Add(lines[0]);
}
private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
textBox1.Text = lines[1];
}
ok problem is lines[1] only reads the end of the array and i allways get the last result no matter what i do to try to change it, but lines[0] works fine??? how can i get the textbox to only show the right thing based on what lines[0] is.
example lines[0] = 1
how can i get lines[1] to display the first line.
lines[0] = 2
how can i get lines[1] to display the 2nd line and so forth.解决方案or at least tell me how i can do this
string[,] threebythree = new string[Int16.Parse(ID[i]), Int16.Parse(lines[i])];
because even with the conversions i get
ERROR: Input string was not in a correct format.
Not exactly sure what the goal here is... But looks like if you pick the second item from a list box (iteration 1 since it is zero indexed) that you want the second line of your file to appear in a text box. Fourth item selected in the listbox = fourth item in the text box. Is that the goal?
Both are zero-indexed. So take the .SelectedIndex value from the listbox and use that as the line number index to show in the text box.
If I have mis-understood your goal and lead you astray, my deepest apologies.
sry i said it in a confusing way.
The text file has this in it:
0 string1 5
1 string2 10
2 string3 15
lines[0] is 0, 1, 2
lines[1] is string1, string2, string3
lines[2] is 5, 10, 15
ID[0] is 0 string1 5
ID[1] is 1 string2 10
ID[2} is 2 string3 15
when i try to write lines[1] to textbox1.text im getting string3 only.
i dont know the code to make it string1 first then string2, then string3.
so its reading the last array first.
i would like to make it possible to just have an array like (ID[i], lines[i]) thats what i tried doing in the reply but of course that doesnt work.
