Expression-Bodied Members vs. Lambda Expressions: What's the Difference in C#'s `=>` Operator Usage?

Field initialization

public int MaxHealth
{
    get
    {
        return Memory[Address].IsValid ? Memory[Address].Read<int>(Offs.Life.MaxHp) : 0;
    }
}

In the field initialization, the

operator is not used. Instead, the traditional grammar is assigned to the field.

public int MaxHealth = x ? y : z;

The key difference between

public int MaxHealth; // 字段声明
public int MaxHealth = x ? y : z; // 字段赋值

The initialization of the expression member and the field is the scope and the timing of value. Expressive members define a attribute Getter (or method), which will be executed every time access attributes. On the other hand, the field initialization is set only once the field value is set when instantiated type.

Lambda expression

In the Lambda expression, the

operator is used to separate the input parameters of the anonymous function from its subject. Lambda expression is used to define anonymous method or expression that can be passed to other functions as parameters. They have nothing to do with expression members.
