## 备注

使用此函数获取 [XtfGetCredentialInfoList](/reference/tools/xtf/xtfapi/functions/xtfgetcredentialinfolist-xtfapi-xbox-windows-m) 函数返回的 `XtfNetworkCredentials` 对象中存储的凭据数量。将此函数与 `XtfGetCredentialInfoList`、[XtfGetCredentialServerName](/reference/tools/xtf/xtfapi/functions/xtfgetcredentialtargetname-xtfapi-xbox-windows-m) 和 [XtfGetCredentialUserName](/reference/tools/xtf/xtfapi/functions/xtfgetcredentialusername-xtfapi-xbox-windows-m) 函数一起使用，以枚举主机上当前存储的凭据列表。你还可以使用 [XtfAddCredential](/reference/tools/xtf/xtfapi/functions/xtfaddcredential-xtfapi-xbox-windows-m) 添加凭据，使用 [XtfRemoveCredential](/reference/tools/xtf/xtfapi/functions/xtfremovecredential-xtfapi-xbox-windows-m) 移除凭据。

完成后，使用 [XtfCloseCredentialInfoList](/reference/tools/xtf/xtfapi/functions/xtfclosecredentialinfo-xtfapi-xbox-windows-m) 释放由 `XtfGetCredentialInfoList` 返回的 `XtfNetworkCredentials` 对象。

有关演示如何管理和枚举已存储凭据的示例，请参阅 [XtfGetCredentialInfoList](/reference/tools/xtf/xtfapi/functions/xtfgetcredentialinfolist-xtfapi-xbox-windows-m)。
