字串與字串 C#

文字表示稱為字串。它是字元的組合，否則稱為變數。字串是從字母表中選擇的，並且始終採用字母字元。該字串被視為資料類型數組。它也是數組的表示。字串中的變數允許靜態或動態分配記憶體。字串在C#中被用作類，是Unicode字元或字元陣列的組合。我們可以將字元數組稱為文本，就像使用字母表一樣，並形成有意義的單字。字串是一個關鍵字，與類別一起使用。

以下是 String 與 String C# 之間的前 16 個比較：

String 和 String C# 之間的主要差異

讓我們在以下幾點討論 String 與 String C# 之間的一些關鍵差異：

• 字串類別需要在檔案中導入系統命名空間，而字串變數不需要宣告它。 System 命名空間幫助程式輕鬆地從 C# 匯入到 VB.NET。
• 字串是型別類，而字串是 C# 中的詞法建構。
• 必須為字串定義指令，而字串變數則完全不需要。
• 它被寫成字串和字串。格式 () 或 System.字串。
• 字串是 CLR 中的型別，而字串是 C# 中的型別。當 C# 和 CLR 一起使用時，System.該字串會自動使用。
• 字串是 .NET Framework 中的資料型別，而字串是 C# 中的資料型態。
• 對於變數聲明，使用字串，對於類別聲明 System.使用了字串。
• 字串在System中是引用類型，而字串作為變數不能用來引用C#中的任何資料或類型。
• 字串可以引用任何內容，取決於用法。但字串是一個關鍵字，不能用於聲明任何變量，它始終具有正確的用法含義。
• 當需要靜態函數時，最好使用 System.細繩。字串作為變數可以用於變數的使用和正確的編碼風格。
• 關鍵字 string 僅用於建立變量，在 C# 中使用有限。系統。字串有一組不同的函數和屬性來更改字串變數。
• 當使用字串來宣告變數時，String 用於存取 C# 中的靜態方法，例如 String。 Format() 和 String.比較()等等。
• Clojure 的數字字面值編譯時有或沒有邊界檢查，而 Scala 的數位編譯並不像這麼複雜。
• 字串總是對應到 System. String，而 String 不需要對應到任何變數或類別。
• 當使用字串時，它只是用於變數聲明，但在程式碼中使用 String 時，它有多種用途。

字串與C#字串對照表

下表總結了 String 與 String C# 之間的比較:

String	String in C#
A string is a reserved word. Hence we cannot use string as a variable name.	A string is a class name.
The system is not needed to use a string variable.	A string cannot be used with writing using System. When it is created, it should be used to declare the variable and hence the type is different.
To declare a variable, the string is used.	A string is used when a method is called or declared.
The variable string always points to System. string.	System string can take cues from string or any other data type, and it is not always reserved for string variable alone.
The bugs are less and not common in the string.	The bugs are common, and to fix bugs, we have to go through the entire code as it takes the response from all the data types.
The meaning of string depends on the variable it carries.	The meaning of String depends on the source code or the referenced type in the assemblies of the project.
Developers can easily interpret the string as it reserves only a few data types.	It takes time for developers to interpret the code using String, and it may take hours to solve the issues related to System string.
While declaring string, it will throw an error if the other side variable is not defined.	It depends on the codebase to show the error as in some cases, String does not need the variable to be declared, and in some cases, it asks for it.
A string is not defined with any regularity, and it shows an error if the variable is not defined properly.	The string is defined with some regularity as it takes the types from all the reserved data types and cross verifies the same.
A string has only one purpose, and it is to declare the variable in the program.	The string has various purposes regarding class declaration, libraries, serialization, reflections, helpers, lexical constructs, etc.
The string is used for local declarations.	The string is used for static methods.
The string has better readability and is understood well by all developers as a variable declaration.	The readability is not good, and as it is used for many purposes; developers are often confused with the usage.
The usage of the string is limited, and hence the compilation time is less for the program.	The usage of String is vast, and hence it takes a long time to compile the program.
Once when we declare a variable, we cannot change it, and hence a new variable has to be declared. The string is immutable.	Strings are mutable, and we can use them repetitively for many purposes in the coding regime.
Since strings are used for a single purpose and are immutable, the usage of the string is costly.	Strings can be used more than once, and we can say that the usage of Strings is not a costly affair.
Optimization of a string is not good and takes time.	It provides a better way to optimize Strings.

結論

字串和字串變數在大多數方面都很相似，例如效能、用法（除了上面指出的以外）。然而，在大多數情況下，字串變數是首選，因為它很容易突出顯示語法。  當 C# 編譯器與 Java 位元組程式碼一起使用時，編譯器會對應為字串或 System.字串。
