By using readonly, we can set a value in the constructor or in the initial number, which will not be modified after this value.
For example, we set a property called Color to Readonly:
Public Static Readonly Color Red;
Structs
The Struct in C # is a synthetic data type, consisting of some elements or data types. We can compare it to user-defined types in VB. such as:
Struct Point
{
Public int x;
Public int y;
}
Then you can reference this Struct as follows:
Point P1;
P1.x = 10;
P1.y = 10
AS
The AS operator is used to check the type of the left operand, if possible, convert it into the right operand. such as:
INT A as b;
If 'A' can be converted into 'b', this conversion is performed.
IF
There is no 'Then' or 'elseif' statement in C #, which is not like VB. The following is a comparison of the IF statement in VB and C #:
In VB:
IF size <60 then
Value = 50
END IF
In C #:
IF (SIZE <60);
Value = 50;
