方法' FeedShare'需要的6 & # 39;Facebook SDK v7.1.0 Unity

我正在与Facebook共享游戏，但我一直得到这个错误:

方法FeedShare' takes 6'参数不能重载

我的代码

using UnityEngine;
using System.Collections;
using System.Collections.Generic;
using Facebook.Unity;
public class FBHolder : MonoBehaviour {
void Awake ()
{
        FB.Init (SetInit, OnHideUnity);
}
private void SetInit ()
{
    Debug.Log ("Facebook Init done");
    if (FB.IsLoggedIn) {
        Debug.Log ("Facebook logged in");
    } else {
        FBLogin();
    }
}
private void OnHideUnity (bool isGameShown)
{
    if (!isGameShown) {
        Time.timeScale = 0;
    } else {
        Time.timeScale = 1;
    }
}
void FBLogin()
{
    var perms = new List<string> (){"public_profile", "email", "user_friends"};
    FB.LogInWithReadPermissions (perms, AuthCallback);
}
private void AuthCallback (ILoginResult result) {
    if (FB.IsLoggedIn) {
        Debug.Log("FB Login Worked");
        // share facebook
        FB.FeedShare(
            link: "https://enterlinkhere.com",
            linkName: "PollyCube",
            linkCaption: "LinkCaption",
            linkDescription: "LinkDescription",
            picture: "https://enterimagehere.com",
            callback: LogCallback
            );
    }
    else {
        Debug.Log("User cancelled login");
    }
}

void LogCallback(IResult response) {
    Debug.Log("Worked");
}

}

这是Facebook Feedshare的代码(也在我上面发布的代码中)

            FB.FeedShare(
            link: "https://enterlinkhere.com",
            linkName: "PollyCube",
            linkCaption: "LinkCaption",
            linkDescription: "LinkDescription",
            picture: "https://enterimagehere.com",
            callback: LogCallback
            );
    void LogCallback(IResult response) {
    Debug.Log("Worked");
}

我使用这个文档来做这个，以防你想知道我从哪里得到这个

https://developers.facebook.com/docs/unity/reference/current/FB.FeedShare

FB.FeedShare(
        string.Empty, //toId
        new System.Uri("https://enterlinkhere.com"), //link
        "PollyCube", //linkName
        "LinkCaption", //linkCaption
        "LinkDescription", //linkDescription
        new System.Uri("https://enterimagehere.com"), //picture
        string.Empty, //mediaSource
        LogCallback //callback
        );
