Matn faylidan o'qish va yozish. StreamReader va StreamWriter

• Task ReadAsync(): Read metodining asinxron versiyasi;
• string ReadLine(): faylda bitta satr o'qiydi;
• string ReadLineAsync(): ReadLine metodining asinxron versiyasi;
• string ReadToEnd(): fayldagi barcha matnni o'qiydi;
• string ReadToEndAsync(): ReadToEnd metodining asinxron versiyasi;

Dastlab, matnni mavjud fayldan to'liq o'qiymiz :

Matnni fayldan satrlab o'qish:

string path= @"C:\SomeDir\hta.txt";

using (StreamReader sr = new StreamReader(path, System.Text.Encoding.Default))

{

string line;

while ((line = sr.ReadLine()) != null)

{ Console.WriteLine(line); }

}

// asinxron o'qish

using (StreamReader sr = new StreamReader(path, System.Text.Encoding.Default))

{

string line;

while ((line = await sr.ReadLineAsync()) != null)

{ Console.WriteLine(line); }
