添加張貼圖像縮略圖到Wordpress博客與JoeBlogs/C＃

Question

我試圖用拇指圖像添加新帖子，但我仍然無法取得成功。

public static int addContent(int postType, string title, string body, string post_thumbnail, string[] categories, string[] tags, DateTime dateCreated) 
{ 
    Post post = setPost(postType, title, body, post_thumbnail, categories, tags, dateCreated); 
    using (var wrapper = getWordPressWrapper()) 
    { 
    return wrapper.NewPost(post, true); 
    } 
} 

得到setPost方法，

public static Post setPost(int postType, string title, string body, string post_thumbnail, string[] categories, string[] tags, DateTime dateCreated) 
{ 
    string type = postType == 1 ? "post" : "page"; 
    var customFields = new CustomField[] { 
    new CustomField() { 
     // Don't pass in ID. It's auto assigned for new custom fields. 
     // ID = "name", 
     Key = "post_thumbnail", 
     Value = post_thumbnail 
    } 
    //, 
    //  new CustomField() { 
    // // Don't pass in ID. It's auto assigned for new custom fields. 
    // // ID = "name", 
    // Key = "post-thumbnail", 
    // Value = post_thumbnail 
    //} , 
    //  new CustomField() { 
    // // Don't pass in ID. It's auto assigned for new custom fields. 
    // // ID = "name", 
    // Key = "post-thumbnails", 
    // Value = post_thumbnail 
    //} , 
    //  new CustomField() { 
    // // Don't pass in ID. It's auto assigned for new custom fields. 
    // // ID = "name", 
    // Key = "thumbnail", 
    // Value = post_thumbnail 
    //} 
    }; 
    return new Post 
    { 
    PostType = type, 
    Title = title, 
    Body = body, 
    Categories = categories, 
    Tags = tags, 
    DateCreated = dateCreated, 
    CustomFields = customFields 
    }; 
} 

當你看到它的評論。我嘗試了一切發佈拇指圖像。

我試過post_thumbnail，後縮略圖，後縮略圖，縮略圖鍵，但沒有發生。

我該怎麼做？

假設縮略圖已經上傳了，你知道它的介質ID，

Key = "_thumbnail_id", 
Value = id_of_uploaded_thumbnail 

應該工作。
