使用StreamReader从文件读取数据到第1行的数组中

Question

 StreamReader text = new StreamReader(@textBox1.Text.ToString());
        String tempArray = text.ReadToEnd();
        char[] charA = tempArray.ToCharArray();
        Console.Write(charA);

output is like that

****4****
**26*71**
871***694
*6*****4*
2*59*67*8
*8*****2*
658***471
**94*85**
****7****

but ı want to write and save 1d array on 1 row simple ;

****4**** 26*71 871***694 *6*****4* 2*59*67*8 *8*****2* 658***471 94*85 ****7****

how can ı split this ?

There's a lot going on in the code you've shared:

StreamReader text = new StreamReader(@textBox1.Text.ToString());
String tempArray = text.ReadToEnd();
char[] charA = tempArray.ToCharArray();
Console.Write(charA);

textBox1.Text already is a string , so you don't need the .ToString() behind that.

By the way you don't need to prefix a field with a @ unless it's the field has the same name as a keyword. You're free to do it anyway if you like, though).

StreamReader text = new StreamReader(textBox1.Text);
String tempArray = text.ReadToEnd();
char[] charA = tempArray.ToCharArray();
Console.Write(charA);

Next, if all you want to do with the file is read all its contents as a string , you might want to use File.ReadAllText() as it doesn't keep the file open:

String tempArray = File.ReadAllText(textBox1.Text);
char[] charA = tempArray.ToCharArray();
Console.Write(charA);

The console outputs multiple lines but the char[] still really is a 1D array. The problem is that there are newline characters in the file, which get processed by the console.

If you want to remove these newlines, it's easier to do so while you're still working with a string - because there are quite a few built-in features for this. Someone already commented using string.Replace("\\r\\n", "") to do this trick:

String tempArray = File.ReadAllText(textBox1.Text);
tempArray = tempArray.Replace("\r", "");
tempArray = tempArray.Replace("\n", "");
char[] charA = tempArray.ToCharArray();
Console.Write(charA);
