template.Run(object model = null) template.RunAsync(object model = null) template.Run<TModel>(TModel model = null) template.RunAsync<TModel>(TModel model = null)
💥 HTML Safety
RazorEngineCore is not HTML safe by default.
It can be easily turned on: see #65 and @Raw
Examples
Basic usage
IRazorEngine razorEngine = new RazorEngine();
IRazorEngineCompiledTemplate template = razorEngine.Compile("Hello @Model.Name");
string result = template.Run(new
{
Name = "Alexander"
});
Console.WriteLine(result);
Strongly typed model
IRazorEngine razorEngine = new RazorEngine();
string templateText = "Hello @Model.Name";
// yeah, heavy definition
IRazorEngineCompiledTemplate<RazorEngineTemplateBase<TestModel>> template = razorEngine.Compile<RazorEngineTemplateBase<TestModel>>(templateText);
string result = template.Run(instance =>
{
instance.Model = new TestModel()
{
Name = "Hello",
Items = new[] {3, 1, 2}
};
});
Console.WriteLine(result);
Save / Load compiled templates
Most expensive task is to compile template, you should not compile template every time you need to run it
IRazorEngine razorEngine = new RazorEngine();
IRazorEngineCompiledTemplate template = razorEngine.Compile("Hello @Model.Name");
// save to file
template.SaveToFile("myTemplate.dll");
//save to stream
MemoryStream memoryStream = new MemoryStream();
template.SaveToStream(memoryStream);
IRazorEngineCompiledTemplate template1 = RazorEngineCompiledTemplate.LoadFromFile("myTemplate.dll");
IRazorEngineCompiledTemplate template2 = RazorEngineCompiledTemplate.LoadFromStream(myStream);
IRazorEngineCompiledTemplate<MyBase> template1 = RazorEngineCompiledTemplate<MyBase>.LoadFromFile<MyBase>("myTemplate.dll");
IRazorEngineCompiledTemplate<MyBase> template2 = RazorEngineCompiledTemplate<MyBase>.LoadFromStream<MyBase>(myStream);
Caching
RazorEngineCore is not responsible for caching. Each team and project has their own caching frameworks and conventions therefore making it impossible to have builtin solution for all possible needs.
If you dont have one, use following static ConcurrentDictionary example as a simplest thread safe solution.
private static ConcurrentDictionary<int, IRazorEngineCompiledTemplate> TemplateCache = new ConcurrentDictionary<int, IRazorEngineCompiledTemplate>();
private string RenderTemplate(string template, object model)
{
int hashCode = template.GetHashCode();
IRazorEngineCompiledTemplate compiledTemplate = TemplateCache.GetOrAdd(hashCode, i =>
{
RazorEngine razorEngine = new RazorEngine();
return razorEngine.Compile(Content);
});
return compiledTemplate.Run(model);
}
Template functions
ASP.NET Core way of defining template functions:
<area>
@{ RecursionTest(3); }
</area>
@{
void RecursionTest(int level)
{
if (level <= 0)
{
return;
}
<div>LEVEL: @level</div>
@{ RecursionTest(level - 1); }
}
}
output:
<div>LEVEL: 3</div>
<div>LEVEL: 2</div>
<div>LEVEL: 1</div>
Helpers and custom members
string content = @"Hello @A, @B, @Decorator(123)";
IRazorEngine razorEngine = new RazorEngine();
IRazorEngineCompiledTemplate<CustomTemplate> template = razorEngine.Compile<CustomTemplate>(content);
string result = template.Run(instance =>
{
instance.A = 10;
instance.B = "Alex";
});
Console.WriteLine(result);
public class CustomTemplate : RazorEngineTemplateBase
{
public int A { get; set; }
public string B { get; set; }
public string Decorator(object value)
{
return "-=" + value + "=-";
}
}
Referencing assemblies
Keep your templates as simple as possible, if you need to inject "unusual" assemblies most likely you are doing it wrong.
Writing @using System.IO
in template will not reference System.IO assembly, use builder to manually reference it.
IRazorEngine razorEngine = new RazorEngine();
IRazorEngineCompiledTemplate compiledTemplate = razorEngine.Compile(templateText, builder =>
{
builder.AddAssemblyReferenceByName("System.Security"); // by name
builder.AddAssemblyReference(typeof(System.IO.File)); // by type
builder.AddAssemblyReference(Assembly.Load("source")); // by reference
});
string result = compiledTemplate.Run(new { name = "Hello" });
Debugging templates
In the builder options, set GeneratePdbStream to true, and set the TemplateFilename.
razorEngine.Compile(templateSource, builder =>
{
builder.Options.GeneratePdbStream = true;
builder.Options.TemplateFilename = "TemplateFilename.cshtml"
});
Your debugger will popup a window asking you to find the source file, after which you can step through as normal.
To set a breakpoint add this line in a code block in the template.
System.Diagnostics.Debugger.Break();
