将项目移动到.Net Core时,AddHeader会抛出错误：

Error CS1061 ‘HttpResponse’ does not contain a definition for
‘AddHeader’ and no extension method ‘AddHeader’ accepting a first

例子：

string combineValue = httpContext.Request.Headers["header1];
if (string.IsNullOrEmpty(combineValue)) // ...
var values = httpContext.Request.Headers["header1"];
if (StringValues.IsNullOrEmpty(values)) // ...
httpContext.Response.Headers["CustomHeader1"] = "singleValue";
httpContext.Response.Headers["CustomHeader2"] =  new[] { "firstValue","secondValue" };
