在Scriban模板引擎中替换字典值遇Render错误求解答

我来帮你排查这个问题——你在Render行遇到的错误，核心是两个小细节问题，咱们一步步解决：

错误原因分析 #

你写的keyValuePairs[emailContent]里，emailContent没有加引号，编译器会把它当成一个未定义的变量，这肯定会触发编译错误。另外，其实还有更简洁的方式传递数据源给Scriban，不用手动从字典取值再构建匿名对象。

修正方案1：修复索引语法 #

如果想保留原有的匿名对象传递方式，只需要把索引改成字符串字面量即可：

string bodyText = "Hi, The following service(s) has reported issues. {{emailContent}} Thanks ";
Dictionary<string, string> keyValuePairs = new Dictionary<string, string>() { {"emailContent", "UserManagement has following unhealthy subservice(s)"} };
var template1 = Template.Parse(bodyText);
// 这里把emailContent改成字符串字面量"emailContent"
var result1 = template1.Render(new { emailContent = keyValuePairs["emailContent"] });
Console.WriteLine(result1.ToString());

修正方案2：直接传入字典（更简洁） #

Scriban支持直接把字典作为数据源传入，模板会自动匹配键名，省去构建匿名对象的步骤：

string bodyText = "Hi, The following service(s) has reported issues. {{emailContent}} Thanks ";
Dictionary<string, string> keyValuePairs = new Dictionary<string, string>() { {"emailContent", "UserManagement has following unhealthy subservice(s)"} };
var template1 = Template.Parse(bodyText);
// 直接传递字典，模板会自动解析键"emailContent"对应的值
var result1 = template1.Render(keyValuePairs);
Console.WriteLine(result1.ToString());

这两种方式都能正常渲染出你想要的结果：Hi, The following service(s) has reported issues. UserManagement has following unhealthy subservice(s) Thanks
