如何在Mvc Core3中通过UserManager获取一个角色的所有用户？

using Microsoft.AspNetCore.Identity;

private readonly UserManager<IdentityUser> _userManager;
private readonly RoleManager<IdentityRole> _roleManager;

public YourController(UserManager<IdentityUser> userManager, RoleManager<IdentityRole> roleManager)
{
    _userManager = userManager;
    _roleManager = roleManager;
}

public async Task<IActionResult> GetUsersInRole(string roleName)
{
    var role = await _roleManager.FindByNameAsync(roleName);
    
    if (role != null)
    {
        var users = await _userManager.GetUsersInRoleAsync(role.Name);
        
        // 处理获取到的用户列表
        // ...
        
        return View(users);
    }
    
    return NotFound();
}
