在C＃中，可以使用ASP.NET Core中的Authorization策略來自定義Claims。下面是一個示例：
services.AddAuthorization(options =>
{
options.AddPolicy("CustomPolicy", policy =>
{
policy.RequireClaim("CustomClaimType", "CustomClaimValue");
});
});
[Authorize(Policy = "CustomPolicy")]
public IActionResult MyCustomAction()
{
return View();
}
var claims = new List<Claim>
{
new Claim("CustomClaimType", "CustomClaimValue")
};
var userIdentity = new ClaimsIdentity(claims, "login");
var userPrincipal = new ClaimsPrincipal(userIdentity);
await HttpContext.SignInAsync(userPrincipal);
通過以上方法，您可以在C＃中自定義Claims并實現自定義的Authorization策略。
