如何修复 'IMvcBuilder' 不包含 'AddXmlDataContractSerializerFormatters' 的定义
How to fix 'IMvcBuilder' doesn't contain a definition for 'AddXmlDataContractSerializerFormatters'
我有最新的.Net Core v2.1.4。
我试图在 Startup.cs
文件中添加 AddXmlDataContractSerializerFormatters();
,但它报告说 IMvcBuilder
不包含它的定义。
我的startup.cs
:
{
services.AddMvc().AddXmlDataContractSerializerFormatters();
}
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
app.UseMvc();
app.Run(async(context) =>
{
await context.Response.WriteAsync("MVC didn't find anything!");
});
}
AddXmlDataContractSerializerFormatters()
extension method is in the Microsoft.AspNetCore.Mvc.Formatters.Xml
nuget package。确保您将此包含在您的项目中。使用 Nuget 包管理器 UI 或从命令行:
Install-Package Microsoft.AspNetCore.Mvc.Formatters.Xml
此外,确保您导入的命名空间具有:
using Microsoft.Extensions.DependencyInjection;
