Azure表存储SaveChanges返回“请求的操作未在指定的资源上实现”。

Question

调用save以下天青表对象：

public class MyEntity : TableServiceEntity 
{ 
    public string Title { get; set; } 

    public string Description { get; set; } 

    public float Amount { get; set; } 

    public DateTime CreatedAt { get; set; } 

    public DateTime UpdatedAt { get; set; } 
}

Answer 1

的问题是，浮点存储还没有为Azure存储表来实现。将amount类型更改为double将解决该问题。

public class MyEntity : TableServiceEntity 
{ 
    public string Title { get; set; } 

    public string Description { get; set; } 

    public double Amount { get; set; } // <-- Note change here!!! 

    public DateTime CreatedAt { get; set; } 

    public DateTime UpdatedAt { get; set; } 
}
