The two major data types in C

#The data types in C# are divided into two major categories: Value type and Reference type .

Value type

• Store in the stack
• Copy data directly
• Modifying the value type will not affect other variables
• Includes: integers, floating point numbers, Boolean values, structures, enumerations
• Example:

<code class="c#">int i = 10;
int j = i;
i = 20;
Console.WriteLine(j); // 输出 10</code>

Reference type

• Stored in the heap
• Storing references to objects
• Modifying the reference type will affect other variables
• Including: classes, interfaces, arrays, strings
• Example:

<code class="c#">string s1 = "Hello";
string s2 = s1;
s1 += " World";
Console.WriteLine(s2); // 输出 Hello</code>
