</p> <> C# in the dual identity of the operator: the expression of the operator: the expression member and the lambda expression <p> <strong>
</strong> In C#, </p> The computing character has two very different uses: <p>
<code>=></code> expression member work </p>
<h3> In the expression member's work, the </h3> separate the property or method name is separated from its subject. This grammar allows a single expression to define members without using large brackets and individual GET/SET blocks. <p>
<code>=></code>
</p> <效> Wait for: <pre class='brush:php;toolbar:false;'>public int MaxHealth => Memory[Address].IsValid ? Memory[Address].Read<int>(Offs.Life.MaxHp) : 0;</pre> <p>
<strong>
</strong> Field initialization </p>
<pre class='brush:php;toolbar:false;'>public int MaxHealth
{
get
{
return Memory[Address].IsValid ? Memory[Address].Read<int>(Offs.Life.MaxHp) : 0;
}
}</pre> In the field initialization, the <h3> operator is not used. Instead, the traditional grammar is assigned to the field. </h3>
<p>
<code>=></code> <效> Wait for: </p> <pre class='brush:php;toolbar:false;'>public int MaxHealth = x ? y : z;</pre>
<p>
<strong> <键> Key differences: </strong> </p>
The key difference between <pre class='brush:php;toolbar:false;'>public int MaxHealth; // 字段声明
public int MaxHealth = x ? y : z; // 字段赋值</pre> 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. <p>
<strong> Lambda expression </strong>
</p> In the Lambda expression, the <p> 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. </p>](https://img.php.cn/upload/article/000/000/000/173825017581120.jpg?x-oss-process=image/resize,p_40)
