【问题描述】：
我正在使用RazorEngine 包来生成电子邮件模板。
以下是该方法的代码：
public async Task<string> GetEmailTemplateAsString<T>(string viewName, T model)
{
var templatePath = @$"{Directory.GetCurrentDirectory()}\Views\{viewName}.cshtml";
var template = await File.ReadAllTextAsync(templatePath);
var html = Engine.Razor.RunCompile(template, "weeklySummary", typeof(T), model);
return html;
}
还有观点：
@model CourseWork.Core.Models.EmailTemplate.WeeklySummaryModel
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
<style>
body {
background-color: lightgoldenrodyellow;
font-family: Verdana, Geneva, Tahoma, sans-serif;
}
.greetings {
text-align: center;
border-bottom: 1px solid lightgray;
}
.main {
display: block;
border-bottom: 1px solid lightgray;
text-align: center;
padding-bottom: 21.28px;
}
ul {
list-style: none;
padding: 0;
margin: 0;
}
li {
display: block;
padding: 10px;
}
</style>
</head>
<body>
<section class="greetings">
<h1>Hello, @Model.User.DisplayName!</h1>
<h3>Here is our weekly summary, specially for you</h3>
</section>
<section class="main">
@foreach (var entry in Model.BoardThreadWithRepliesModels)
{
<h4>@entry.BoardName</h4>
<h5>@entry.ThreadName</h5>
<ul>
@foreach (var reply in entry.Replies)
{
<li>
<span>@reply.UserDisplayName</span>
<p>@reply.Content</p>
<img src="@reply.PicRelatedPath" alt="pic-related" />
</li>
}
</ul>
}
</section>
</body>
</html>
运行应用程序后，我收到 CS0103 错误，问题标题中所述的描述。
我尝试在谷歌上搜索错误消息，但主要是所有结果都与 IntelliSense 不起作用有关，这根本不是我的情况。
更新： 调用代码：
*Dapper query*
var fullModel = new WeeklySummaryModel
{
User = user,
BoardThreadWithRepliesModels = models
};
return await _emailTemplateHelper.GetEmailTemplateAsString("WeeklySummary", fullModel);
UPD2： 异常指出第 14 行第 18 行存在问题。结果它位于自动生成的代码中：

【问题讨论】：
-
您是否验证过模型的 type 与
typeof(T)匹配？包含调用此方法的代码可能会有所帮助。我有非常相似的代码，没有问题 -
@ChrisSchaller，是的，类型是一样的。
-
在编译时定义模型类型没有帮助。
-
您也可以尝试使其不输入：
Engine.Razor.RunCompile(template, "weeklySummary", null, model) -
抛出同样的错误。
