How to access property of anonymous type in C#?

To access the property of an anonymous type in C#, you can use the var keyword to declare the anonymous type, and then access its properties using dot notation. For example:

 var person = new { Name = "John", Age = 30 }; Console.WriteLine(person.Name); // Output: John

If you need to pass the anonymous type as a parameter to a method or return it from a method, you can use object as the type, as anonymous types are implicitly converted to object. For example:

 public static object CreateAnonymousType() { return new { Name = "John", Age = 30 }; } var person = CreateAnonymousType(); Console.WriteLine(person.GetType()); // Output: <Anonymous Type> Console.WriteLine(person.Name); // Error: 'object' does not contain a definition for 'Name'

To access the property of the anonymous type in the above example, you need to cast it back to the anonymous type first:

 var person = (new { Name = "John", Age = 30 }); Console.WriteLine(person.GetType()); // Output: <Anonymous Type> Console.WriteLine(person.Name); // Output: John

  1. "C# access anonymous type property by reflection"

    • Description: Learn how to access properties of an anonymous type using reflection.
    // Code Implementation: var anonymousObject = new { Name = "John", Age = 30 }; var type = anonymousObject.GetType(); var propertyInfo = type.GetProperty("Name"); var value = propertyInfo.GetValue(anonymousObject);

  2. "C# access anonymous type property using dynamic"

    • Description: Use the dynamic keyword to access properties of an anonymous type.
    // Code Implementation: var anonymousObject = new { Name = "John", Age = 30 }; dynamic dynamicObject = anonymousObject; var name = dynamicObject.Name;

  3. "C# access anonymous type property in LINQ query"

    • Description: Access properties of an anonymous type within a LINQ query.
    // Code Implementation: var result = from person in people select new { person.Name, person.Age }; foreach (var item in result) { var name = item.Name; var age = item.Age; }

  4. "C# access nested anonymous type property"

    • Description: Access properties of a nested anonymous type using the dynamic keyword.
    // Code Implementation: var parentObject = new { Child = new { Property = "Value" } }; dynamic dynamicParent = parentObject; var value = dynamicParent.Child.Property;

  5. "C# access anonymous type property by name"

    • Description: Access properties of an anonymous type dynamically using a property name.
    // Code Implementation: var anonymousObject = new { Name = "John", Age = 30 }; var value = anonymousObject.GetType().GetProperty("Name").GetValue(anonymousObject);

  6. "C# access anonymous type property in foreach loop"

    • Description: Iterate through properties of an anonymous type in a foreach loop.
    // Code Implementation: var anonymousObject = new { Name = "John", Age = 30 }; foreach (var property in anonymousObject.GetType().GetProperties()) { var value = property.GetValue(anonymousObject); }

  7. "C# access anonymous type property with null check"

    • Description: Safely access properties of an anonymous type with null checks.
    // Code Implementation: var anonymousObject = new { Name = "John", Age = 30 }; var property = anonymousObject.GetType().GetProperty("Name"); var value = property != null ? property.GetValue(anonymousObject) : null;

  8. "C# access multiple anonymous type properties"

    • Description: Access multiple properties of an anonymous type using the dynamic keyword.
    // Code Implementation: var anonymousObject = new { Name = "John", Age = 30 }; dynamic dynamicObject = anonymousObject; var name = dynamicObject.Name; var age = dynamicObject.Age;

  9. "C# access anonymous type property with type casting"

    • Description: Cast an anonymous type to a known type for accessing its properties.
    // Code Implementation: var anonymousObject = new { Name = "John", Age = 30 }; var typedObject = (dynamic)anonymousObject; var name = typedObject.Name;

  10. "C# access anonymous type property in lambda expression"

    • Description: Access properties of an anonymous type within a lambda expression.
    // Code Implementation: var people = new List<dynamic> { new { Name = "John", Age = 30 }, new { Name = "Alice", Age = 25 } }; var names = people.Select(person => person.Name);
