asp.net – 来自web.config的Asp .Net自定义成员资格参数

public override void Initialize(String name,NameValueCollection config);

System.Collections.NameValueCollection是一个字典,您可以在其中找到web.config文件中编写的选项.这些选项的指定方式与指定“标准”提供程序的选项(作为属性)的方式相同.每个字典条目都具有属性名称的键,并且具有属性值(作为字符串)的值.

public  class MymembershipProvider : MembershipProvider
{
    public override void Initialize(String name,NameValueCollection config)
    {
        base.Initialize(name,config);

        _enablepasswordReset = config.GetBoolean("enablepasswordReset",truE);
    }
}

在我的例子中,GetBoolean()是一个在下面声明的扩展方法：

public static bool GetBoolean(this NameValueCollection config,String valuename,bool? DefaultValuE)
{
    object obj = config[valuename];
    if (obj == null)
    {
        if (!DefaultValue.Hasvalue)
            throw new WarningException("required field has not been specified.");

        return DefaultValue.Value;
    }

    bool value = DefaultValue;
    if (obj is Boolean)
        return (bool)obj;

    IConvertible convertible = obj as IConvertible;
    try
    {
        return convertible.ToBoolean(CultureInfo.InvariantCulturE);
    }
    catch (Exception)
    {
        if (!DefaultValue.Hasvalue)
            throw new WarningException("required field has invalid format.");

        return DefaultValue.Value;
    }
}
