何时在ASMX中实例化SoapHeader字段？

Question

请考虑以下事项：

public MyCustomHeader MyHeader;

public New()
{
    //MyHeader is NOT instantiated
}


[SoapHeader("MyHeader")]
[WebMethod()]
public bool MyFunction()
{
    //MyHeader is instantiated, but when was it instantiated?
}

Answer 1

对于您的示例，它将在执行MyFunction方法之前进行实例化。由于Header需要能够执行MyFunction的操作。
