Class variables, commonly known as static variables, are defined using the static keyword in a class but outside a method, constructor (default or parameterized), or block.
Private static variables are frequently utilized for constants. For example, many individuals prefer not to use constants in their code. Instead, they prefer to create a private static variable with a meaningful name and utilize it in their code, making the code more understandable.
If a variable is declared static, then the variable’s value is the same for all the instances, and we don’t need to create an object to call that variable.
In the above example, we created a static private variable and printed its value.
Let us understand an example to see the difference between a private and a private static variable.
The PersonB object changes the eye variable in the above example, but the leg variable remains the same. This is because a private variable copies itself to the method, preserving its original value. But a private static value only has one copy for all methods to share, thus changing its value changes the original value.

C# Static String Use static string fields to cache data and reduce string allocations.
Static string. A static string is stored in one location. It has many differences from regular strings, such as instance strings and local variables.
Readonly Readonly strings can be instance strings or static strings, and can only be assigned in a constructor.
Assign We assign static strings with the assignment operator. This is a bitwise copy of the reference value.
Note When you assign the value of ToString(), data is allocated on the managed heap. The reference now points to that object data.
Program notes. Static and instance strings can be used in other methods on the same type. Static strings can be used by all instance and static methods on the type.
And This is different from const strings, which must be assigned to a constant value.
Keyword notes. Static can be applied to various things in C#. It does not affect the usage of the type. Static things just exist only once, regardless of the number of instances.
A summary. Static strings can be used in C# programs. We described static string usage and how "static" points to only one storage location in a program.
