C# da string metodlari

#csharp #coding #beginners #programming

C# dasturlash tilida har xil String metodlari mavjud.

1.Substring -> string qaytardi va 2 ta integer qabul qiladi. 1-integer qayerdan boshlab olinishi kerakligi uchun kerak(indeks orqali). 2-integer (ixtiyoriy) va u nechta character olish kerakligini belgilaydi.

string message = "Welcome to .Net class"; string part = message.Substring(11, 4); Console.WriteLine(part);
Enter fullscreen mode Exit fullscreen mode

2.Replace -> 2 ta string qabul qiladi. Agarda o'zgartirish kerak bo'lgan belgilarni topa olmasa, original string ni o'zgaruvchiga saqlaydi.

string message = "Welcome to .Net course"; string replacedString = message.Replace(".Net", "English"); Console.WriteLine(replacedString);
Enter fullscreen mode Exit fullscreen mode

3.Compare -> 2 ta string qabul qiladi. 1-stringga qarab, 2-stringni tekshiradi. Return type integer.

int result = string.Compare("apple", "Apple"); Console.WriteLine(result);
Enter fullscreen mode Exit fullscreen mode

4.Contains -> bool qaytaradi(true/false). Bir dona tekshiriladigan string qabul qiladi.

string message = "Welcome to .NET course"; string course = ".NET"; bool hasDotNet = message.Contains(course); Console.WriteLine(hasDotNet);
Enter fullscreen mode Exit fullscreen mode

5.Trim -> yangilangan string qaytaradi. Bo'sh joylarni (Space) boshidan va oxiridan olib tashlaydi.

string name2 = " Rashidov Sanjar "; string updatedname = name2.Trim(); Console.WriteLine(name2);
Enter fullscreen mode Exit fullscreen mode

6.Index -> qidirish uchun string qabul qiladi. Return type integer.

string text = "Hello World!"; int index = text.IndexOf("o");
Enter fullscreen mode Exit fullscreen mode

7.Verbatim -> biror tekst yoki so'zni o'zgartirishlarsiz chop etish uchun foydalanashimiz mumkin. Verbatimni ifodalash uchun "@" belgisidan foydalanamiz.

Console.WriteLine("C:\\Windows\\System32\\calc.exe"); Console.WriteLine(@"C:\\Windows\\System32\\calc.exe"); Console.WriteLine("C:\nWindows\nSystem32\ncalc.exe"); Console.WriteLine(@"C:\nWindows\nSystem32\ncalc.exe");
Enter fullscreen mode Exit fullscreen mode

8.Split -> string ajratgichlari orqali bolaklarga bo'lib beradi, ya'ni alohida qilib ajratadi.

string originalString = "olma,anor,banan"; string mevalar = originalString.Split(','); Console.WriteLine(mevalar[0]); Console.WriteLine(mevalar[1]); Console.WriteLine(mevalar[2]);
Enter fullscreen mode Exit fullscreen mode

9.Join -> stringlarni qoshib chiqarish uchun ishlatiladi. Return type string.

string[] words = {"Salom", "Ilmhub", "Megaschool"}; string joinedText = string.Join(", ", words); Console.WriteLine(joinedText);
Enter fullscreen mode Exit fullscreen mode

10.Remove -> 2 ta integer ya'ni 1-integer(indeks) qayerda boshlanishi, 2-integer nechta character olib tashlash kerakligini aytadi.

string message = "Welcome to English .Net course"; int indexOfDotNet = message.IndexOf(".NET"); string correctedMessage = message.Remove(indexOfDotNet, 5); Console.WriteLine(correctedMessage);
Enter fullscreen mode Exit fullscreen mode

11.StartsWith -> string qabul qiladi, bool qaytaradi. Agarda biz bergan so'z bilan boshlansa true, bomasa false qaytadi.

string mail = "something@gmail.ru"; bool startWith = mail.StartsWith("something"); Console.WriteLine(startWith);
Enter fullscreen mode Exit fullscreen mode

12.EndsWith -> string qabul qiladi, bool qaytaradi. Agarda biz bergan so'z bilan tugasa true, bomasa false qaytadi.

string mail = "something@gmail.ru"; bool endsWith = mail.EndsWith("mail.ru"); Console.WriteLine(endsWith);
Enter fullscreen mode Exit fullscreen mode

13.ToUpper -> string ni katta harflarga o'zgartirib beradi.

string text = "warning!"; Console.WriteLine(text.ToUpper());
Enter fullscreen mode Exit fullscreen mode

14.ToLower -> string ni kichik harflarga o'zgartirib beradi.

string text = "WARNING!"; Console.WriteLine(text.ToLower());
Enter fullscreen mode Exit fullscreen mode
