我有以下类和方法：
public class UserManager<TUser,TKey> : IDisposable
where TUser : class,global::Microsoft.AspNet.Identity.IUser<TKey>
where TKey : global::System.IEquatable<TKey> {
public virtual Task<TUser> FindByIdAsync(TKey userId);
和：
private ApplicationUserManager _userManager;
public ApplicationUserManager UserManager
{
get
{
return _userManager ?? Request.GetOwinContext().GetUserManager<ApplicationUserManager>();
}
set
{
_userManager = value;
}
}
public class ApplicationUserManager : UserManager<ApplicationUser,int>
public class ApplicationUser : IdentityUser<int,CustomUserLogin,CustomUserRole,CustomUserClaim>
var user = await UserManager.FindByIdAsync<ApplicationUser,int>(99);
它给了我错误：
非通用方法
‘Microsoft.AspNet.Identity.UserManager.FindByIdAsync(int)’
cannot be used with type arguments
解决方法
正如错误所述,FindByIdAsync不接受类型参数.这些存在于声明类UserManager< TUser,TKey>
var user = await UserManager.FindByIdAsync(99);
