Implementing Generic Methods

The syntax for creating a Generic Method is as follows:

index.cs


              123
            
returnType methodName<typeParameter1, typeParameter2, ..>(datatype1 arg1, ..) {
    // code here
}

You can have one or more type parameters in a generic method.

We can execute generic methods as follows:

index.cs


              1
            
methodName<typeParameter1, ..>(arg1, ..);

Following is a summary of how we can convert a simple Swap method to a generic method, which can support any data type:

We don't necessarily need to use the type parameters (like T) for defining the arguments. In fact there can be generic methods with no arguments at all:

index.cs


              123
            
void ExampleMethod<A, B, C> () {
    // Code here
}

It is not possible to directly use any kind of operators on arguments or variables defined using generic types:

index.cs


              123
            
void ExampleMethod<A, B> () {
    return A + B; // Error
}

Oliko kaikki selvää?
