从资源读取文本文件

Question

I am trying the following code to split the words in a text file.

The file is written like this:

Apple"Juice"Martini
Lemon"Juice"Party
Banana"Smoothie"Aligns

and the code following:

        string resource_data = Properties.Resources.textfile;
        string[] result = resource_data.Split('"');
        foreach (string lines in result)
        {
            if(comboBox1.Text == result[0])
            {
                richTextBox2.Text = result[2];
            }
        }

Taken & edited from a c++ program I was working on which worked perfectly with the same txt file.

             String^ resource_data = "textfile.txt";
             try
             {
                 StreamReader^ DataIn = File::OpenText(resource_data);
                 String^ DataStr;
                 int count = 0;
                 array<String^>^ result;
                 array<Char>^ separ = gcnew array<Char>{'"'};

                 while((DataStr = DataIn->ReadLine()) != nullptr)
                 {
                     count++;
                     result = DataStr->Split(separ);
                     if(comboBox1->Text == result[0]) // result[0] = Name
                     {

What the code does.. Read each line as it own. Gives first word in each line result[0] as second word on each line is result[1] etc. When I select a word in the combobox I check if it is the same as in the text file and that line is used in result[x]. But in the C# it gives ALL words own result[x] and lines does not matter.

How can I make the following code in c++ to work in C# but having the text file in the resources.resx?

I think I see what the problem is. You first need to split the string resource_data into separate lines. You could do this by splitting resource_data on the new line character(s):

string[] lines = resource_data.Split(new string[1] { Environment.NewLine }, StringSplitOptions.None);
foreach (var line in lines)
{
    string[] parts = line.Split('"');
    if (comboBox1.Text == result[0])
    {
        richTextBox2.Text = result[2];
    }
}

You could also do this using a StringReader:

using (StringReader reader = new StringReader(resource_data))
{
    while (reader.Peek() >= 0)
    {
        string[] parts = reader.ReadLine().Split('"');
        if (comboBox1.Text == result[0])
        {
            richTextBox2.Text = result[2];
        }
    }
}

Additionally if you are only storing the path to the file in the resources, you could open the file and read from it:

using (StreamReader reader = File.OpenText(resource_path)) // path to file
{
    while (reader.Peek() >= 0)
    {
        string[] parts = reader.ReadLine().Split('"');
        if (comboBox1.Text == result[0])
        {
            richTextBox2.Text = result[2];
        }
    }
}
