How to Fix: Update all objects in a collection using LINQ

Update all objects in a collection using LINQ to iterate through each object and update a property.

Quick Answer: Use the ForEach method with a lambda expression to update properties on each object in the collection.

To update all objects in a collection using LINQ, you can utilize the `foreach` loop and the `Select` method. This approach allows for more flexibility and control over the data manipulation process.

foreach (var obj in collection) {
obj.PropertyToSet = value;
}

🔧 Proven Troubleshooting Steps
