CodePudding user response：

In your ASP.NET Core Controller your Delete is expecting a CountryModel. I think you are not supplying it to the request because you don't use it.

public async Task<ActionResult> Delete(int id, CountryModel collection)
{
}

You must remove it so it doesn't expect it. This is why you get the error of method not allowed. Because it can't find a method without the parameter CountryModel. Your method should look like this:

public async Task<ActionResult> Delete (int id)
{
}

CodePudding user response：

From HttpClient.BaseAddress Remarks,

When sending a HttpRequestMessage with a relative Uri, the message Uri will be added to the BaseAddress property to create an absolute Uri.

Note that all characters after the right-most "/" in the base URI are excluded when combined with the message URI. See RFC 3986 Uniform Resource Identifier (URI) Generic Syntax specification.

You don't need to append client.BaseAddress in client.DeleteAsync().

using (var client = new HttpClient())
{
    client.BaseAddress = new Uri("http://192.168.10.34:81/api/");

    var  postTask = await client.DeleteAsync("/Country/"   id);

    ...
}
