C# 方法重载不确定如何重载

我有以下方法：

 public static MvcHtmlString GetQTip(this HtmlHelper htmlHelper, string propertyName, string message, string propertyNameOverride = "", QTipPosition position = QTipPosition.Right, bool includeEvents = true, string title = "")
{
  string qtipPosition = String.Empty;

  switch (position)
  {
    case QTipPosition.Right:
      qtipPosition = "my: 'left center', at: 'right center'";
      break;
    case QTipPosition.Left:
      qtipPosition = "my: 'right center', at: 'left center'";
      break;
    case QTipPosition.Top:
      qtipPosition = "my: 'top middle', at: 'bottom middle'";
      break;
    case QTipPosition.Bottom:
      qtipPosition = "my: 'bottom middle', at: 'top middle'";
      break;
  }

  if (!String.IsNullOrWhiteSpace(propertyNameOverride))
    propertyName = propertyNameOverride;

  if (String.IsNullOrWhiteSpace(title))
    title = htmlHelper.Resource(Resources.Global.Title.Information);

  StringBuilder sb = new StringBuilder();
  sb.Append(String.Concat("$('#", propertyName, "').removeData('qtip').qtip({content: {text:"));
  sb.Append(String.Concat("'", message, "', title: { text: '", title, "', button: false }}, position: { ", qtipPosition, " }"));

  if (includeEvents)
    sb.Append(", show: { event: 'focus mouseenter', solo: true, ready: false }, hide: 'blur'");

  sb.Append(", style: { classes: 'ui-tooltip-shadow ui-tooltip-yellow' } });");

  return new MvcHtmlString(sb.ToString());
}

我怎么称呼这个：

 <%: Html.GetQTip("training-module-name-container-" + module.CategoryId +"-" + module.TrainingModuleId, trainingModulePointsHintText, Zinc.Web.Extensions.QTipPosition.Bottom, true, Html.Resource(Resources.Training.Module.Completed.View.TrainingModulePoints))%>      

我只想要这些参数

谢谢

问题是你不能在中间留下一个参数。可以使用默认参数，但遗漏的参数必须是列表中的最后一个。有关MSDN的说明，请参阅

要解决问题，您有以下几种选择：

1） 将

propertyNameOverride

参数作为函数定义中的最后一个参数，如下所示：

public static MvcHtmlString GetQTip(this HtmlHelper htmlHelper, string propertyName, string message, QTipPosition position = QTipPosition.Right, bool includeEvents = true, string title = "", string propertyNameOverride = "") { 
    // do stuff
}

然后，您可以毫无问题地忽略它

2） 使用参数，但只需将默认值放入：

<%: Html.GetQTip("training-module-name-container-" + module.CategoryId +"-" + module.TrainingModuleId, trainingModulePointsHintText, "", Zinc.Web.Extensions.QTipPosition.Bottom, true, Html.Resource(Resources.Training.Module.Completed.View.TrainingModulePoints))%>

你的问题很模糊。解释你想要达到的目标，以及上面的例子是如何错误的……哦，是的，对不起，我编辑了我的OPS。什么不起作用？您会遇到哪一个错误？不用担心，谢谢，让我试着找出答案：）如果您想用较少的参数调用一个版本的GetQTip，那么您需要创建一个版本的方法，该方法调用原始方法，并为您忽略的参数设置一个默认值。

public static MvcHtmlString GetQTip(this HtmlHelper htmlHelper, string propertyName, string message, QTipPosition position = QTipPosition.Right, bool includeEvents = true, string title = "", string propertyNameOverride = "") { 
    return htmlHelper.GetQTip("training-module-name-container-" + module.CategoryId +"-" + module.TrainingModuleId, trainingModulePointsHintText, "", Zinc.Web.Extensions.QTipPosition.Bottom, true, Html.Resource(Resources.Training.Module.Completed.View.TrainingModulePoints))%>
}
