Создание многострочных строковых литералов

Compiling the Code

Example

string myString1 = "This is the first line of my string.\n" + "This is the second line of my string.\n" + "This is the third line of the string.\n"; string myString2 = @"This is the first line of my string. This is the second line of my string. This is the third line of the string.";

Copy the code and paste it into the Main method of a console application.

В следующем примере представлено два способа создания многострочных строковых литералов.

string myString1 = "This is the first line of my string.\n" + "This is the second line of my string.\n" + "This is the third line of the string.\n"; string myString2 = @"This is the first line of my string. This is the second line of my string. This is the third line of the string.";

Скопируйте код и вставьте его в метод Main консольного приложения.

How to: Search for a String in an Array of Strings

This example calls the IndexOf method on an array of strings to report the string number and index of the first occurrence of a substring.

string[] strArray = {"ABCDEFG", "HIJKLMNOP"}; string findThisString = "JKL"; int strNumber; int strIndex = 0; for (strNumber = 0; strNumber < strArray.Length; strNumber++) { strIndex = strArray[strNumber].IndexOf(findThisString); if (strIndex >= 0) break; } System.Console.WriteLine("String number: {0}\nString index: {1}", strNumber, strIndex);

Copy the code and paste it into the Main method of a console application.

The IndexOf method reports the location of the first character of the first occurrence of the substring. The index is 0-based, which means the first character of a string has an index of 0.

If IndexOf does not find the substring, it returns -1.

The IndexOf method is case-sensitive and uses the current culture.

If you want more control over possible exceptions, enclose the string search in a try-catch statement.

В этом примере вызывается метод IndexOf для массива строк, который сообщает номер строки и индекс первого вхождения подстроки.

string[] strArray = {"ABCDEFG", "HIJKLMNOP"}; string findThisString = "JKL"; int strNumber; int strIndex = 0; for (strNumber = 0; strNumber < strArray.Length; strNumber++) { strIndex = strArray[strNumber].IndexOf(findThisString); if (strIndex >= 0) break; } System.Console.WriteLine("String number: {0}\nString index: {1}", strNumber, strIndex);

Скопируйте код и вставьте его в метод Main консольного приложения.
