命名空间: Microsoft.IdentityModel.Claims
程序集: Microsoft.IdentityModel（microsoft.identitymodel.dll 中）

用法

    Dim identities As ClaimsIdentityCollection
Dim returnValue As IClaimsIdentity

returnValue = ClaimsPrincipal.SelectPrimaryIdentity(identities)

语法

声明
Public Shared Function SelectPrimaryIdentity ( _
    identities As ClaimsIdentityCollection _
) As IClaimsIdentity

public static IClaimsIdentity SelectPrimaryIdentity (
    ClaimsIdentityCollection identities
)

public:
static IClaimsIdentity^ SelectPrimaryIdentity (
    ClaimsIdentityCollection^ identities
)

public static IClaimsIdentity SelectPrimaryIdentity (
    ClaimsIdentityCollection identities
)

public static function SelectPrimaryIdentity (
    identities : ClaimsIdentityCollection
) : IClaimsIdentity

If the identities collection contains a WindowsClaimsIdentity, it is the most preferred. If the identities collection contains an RsaClaimsIdentity, it is the least preferred.

线程安全

此类型的任何公共静态（在 Visual Basic 中为 Shared）成员都是线程安全的。但不能保证任何实例成员是线程安全的。
