Async (Asynchronous)
Definition: Asynchronous programming allows a program to run tasks in the background without blocking the main thread. This is useful for tasks that involve I/O operations, such as reading from a file or making a network request.
Example: Using async keyword in C#:
csharp
Copy
public async Task GetDataAsync()
{
// Asynchronous code here
}
Sync (Synchronous)
Definition: Synchronous programming means that tasks are executed one after another, blocking the main thread until each task completes.
Example: Using synchronous code in C#:
csharp
Copy
public int GetData()
{
// Synchronous code here
}
Void
Definition: The void keyword indicates that a method does not return a value.
Example: A method that performs an action but doesn't return anything:
csharp
Copy
public void PrintMessage()
{
Console.WriteLine("Hello, World!");
}
Await
Definition: The await keyword is used in an asynchronous method to pause execution until a task completes, without blocking the main thread.
Example: Using await with an asynchronous method:
csharp
Copy
public async Task GetDataAsync()
{
var result = await SomeAsyncMethod();
return result;
}
Save
Definition: In the context of databases, Save typically refers to persisting changes to the database, such as saving new records or updating existing ones.
Example: Using Save in Entity Framework:
csharp
Copy
using (var context = new MyDbContext())
{
context.SaveChanges();
}
SaveAsync
Definition: Similar to Save, but used in asynchronous programming to save changes without blocking the main thread.
Example: Using SaveAsync in Entity Framework:
csharp
Copy
using (var context = new MyDbContext())
{
await context.SaveChangesAsync();
}
These concepts are fundamental in modern programming, especially when dealing with I/O-bound operations and improving application responsiveness.
