如何使用joeblogs或xmlrpc添加缩略图图像内容？

添加内容代码：

var post = new Post();
post.DateCreated = DateTime.Today.AddHours(0);
post.Title = textBox1.Text;
post.Body = richTextBox1.Text;
post.Categories = new string[] { secilikat };
var cfs = new CustomField[] 
{ 
        new CustomField() 
        { 
            // Don't pass in ID. It's auto assigned for new custom fields.
            // ID = "name", 
            Key = "post_thumbnail", 
            Value = linkToImage
        } 
};

post.CustomFields = cfs;
