Microsoft.AspNetCore.Mvc.Razor.Host.dll

包:

Microsoft.AspNetCore.Mvc.Razor.Host v1.1.0

在 Razor 的代码生成过程中调用，以生成实例化标记帮助程序的 属性值的代码。 写入的最后一个值不应为 或以分号结尾。

public:
 override void RenderAttributeValue(Microsoft::AspNetCore::Razor::Compilation::TagHelpers::TagHelperAttributeDescriptor ^ attributeDescriptor, Microsoft::AspNetCore::Razor::CodeGenerators::CSharpCodeWriter ^ writer, Microsoft::AspNetCore::Razor::CodeGenerators::CodeGeneratorContext ^ codeGeneratorContext, Action<Microsoft::AspNetCore::Razor::CodeGenerators::CSharpCodeWriter ^> ^ renderAttributeValue, bool complexValue);

public override void RenderAttributeValue (Microsoft.AspNetCore.Razor.Compilation.TagHelpers.TagHelperAttributeDescriptor attributeDescriptor, Microsoft.AspNetCore.Razor.CodeGenerators.CSharpCodeWriter writer, Microsoft.AspNetCore.Razor.CodeGenerators.CodeGeneratorContext codeGeneratorContext, Action<Microsoft.AspNetCore.Razor.CodeGenerators.CSharpCodeWriter> renderAttributeValue, bool complexValue);

override this.RenderAttributeValue : Microsoft.AspNetCore.Razor.Compilation.TagHelpers.TagHelperAttributeDescriptor * Microsoft.AspNetCore.Razor.CodeGenerators.CSharpCodeWriter * Microsoft.AspNetCore.Razor.CodeGenerators.CodeGeneratorContext * Action<Microsoft.AspNetCore.Razor.CodeGenerators.CSharpCodeWriter> * bool -> unit

Public Overrides Sub RenderAttributeValue (attributeDescriptor As TagHelperAttributeDescriptor, writer As CSharpCodeWriter, codeGeneratorContext As CodeGeneratorContext, renderAttributeValue As Action(Of CSharpCodeWriter), complexValue As Boolean)

参数

attributeDescriptor

TagHelperAttributeDescriptor

要为其生成代码的 TagHelperAttributeDescriptor。

writer

CSharpCodeWriter

CSharpCodeWriter用于编写代码的 。

codeGeneratorContext

CodeGeneratorContext

renderAttributeValue

Action<CSharpCodeWriter>

Action 呈现 HTML 属性的原始值。

complexValue

Boolean

指示源属性值是否包含多个简单文本。 false 对于纯 C# 表达式，例如 "PropertyName"。 true 如果属性值至少包含一个内联 Razor 构造，例如 "@(@readonly)"。
