用c＃中的其他文本替换变量文本(replacing a variable text with other text in c#)

用c＃中的其他文本替换变量文本(replacing a variable text with other text in c#)

我使用c＃和sitecore在某些地方基本上使用令牌（请参阅： 如何在sitecore中创建自定义令牌 ）。 我想我有一个解决方案，但我不确定为什么它不起作用，即使我没有错误。

Item tokenItem = Sitecore.Context.Database.Items["/sitecore/content/Site Content/Tokens"]; if (tokenItem.HasChildren) { var sValue = args.FieldValue.ToString(); foreach (Item child in tokenItem.Children) { if (child.Template.Name == "Token") { string home = child.Fields["Title"].Value; string hContent = child.Fields["Content"].Value; if (sValue.Contains(home)) { home.Replace(home, hContent); } } } }

home和hContent拉出每个容器的正确值，但是当页面加载时，它仍然在内容区域输入“home”值（即：@@ sales）而不是新值，该值存储在hContent中。 sValue包含所有内容（表格，div，文本），我试图挑出一个等于“home”的值，并用hContent替换“home”值。 我错过了什么？

I am using c# and sitecore to basically use tokens in certain places ( see: how to create a custom token in sitecore ). I think I have a solution, but am not sure as to why it is not working, even though I am getting no errors.

Item tokenItem = Sitecore.Context.Database.Items["/sitecore/content/Site Content/Tokens"]; if (tokenItem.HasChildren) { var sValue = args.FieldValue.ToString(); foreach (Item child in tokenItem.Children) { if (child.Template.Name == "Token") { string home = child.Fields["Title"].Value; string hContent = child.Fields["Content"].Value; if (sValue.Contains(home)) { home.Replace(home, hContent); } } } }

home and hContent pull up the correct values of each container, but when the page loads, it still has the "home" value inputted (the ie: @@sales) in the content area instead of the new value, which is stored in hContent. The sValue contains everything (tables, divs, text) and I was trying to single out a value that equals to "home" and replace the "home" value with hContent. What am I missing?

如果您的代码是作为RenderField管道的处理器实现的，那么您需要将工作结果放回到args中。 尝试这样的事情：

Item tokenItem = Sitecore.Context.Database.Items["/sitecore/content/Site Content/Tokens"]; if (tokenItem.HasChildren) { var sValue = args.Result.FirstPart; foreach (Item child in tokenItem.Children){ if (child.Template.Name == "Token") { string home = child.Fields["Title"].Value; string hContent = child.Fields["Content"].Value; if (sValue.Contains(home)) { sValue = sValue.Replace(home, hContent); } } } args.Result.FirstPart = sValue; }

请注意，您需要确保在GetFieldValue处理器之后将此处理器修补到管道中。 该处理器负责将字段值拉入args.Result.FirstPart 。

If your code is implemented as a processor for the RenderField pipeline, you need to put the result of your work back into args. Try something like this:

Item tokenItem = Sitecore.Context.Database.Items["/sitecore/content/Site Content/Tokens"]; if (tokenItem.HasChildren) { var sValue = args.Result.FirstPart; foreach (Item child in tokenItem.Children){ if (child.Template.Name == "Token") { string home = child.Fields["Title"].Value; string hContent = child.Fields["Content"].Value; if (sValue.Contains(home)) { sValue = sValue.Replace(home, hContent); } } } args.Result.FirstPart = sValue; }

Note that you need to be sure to patch this processor into the pipeline after the GetFieldValue processor. That processor is responsible for pulling the field value into args.Result.FirstPart.
