从 'double' 到 'System.Runtime.Serialization.ISerializable' 的装箱转换

Boxing conversion from 'double' to 'System.Runtime.Serialization.ISerializable'

我想序列化 class Range<T>,所以我在上面实现了 ISerializable,如下所示:

public class Range<T> where T : IComparable<T>, ISerializable
{
    /// <summary>Minimum value of the range.</summary>
    public T Minimum { get; set; }

    /// <summary>Maximum value of the range.</summary>
    public T Maximum { get; set; }

    /// <summary>Presents the Range in readable format.</summary>
    /// <returns>String representation of the Range</returns>
    public override string ToString()
    {
        return string.Format("[{0} - {1}]", Minimum, Maximum);
    }

    /// <summary>Determines if the range is valid.</summary>
    /// <returns>True if range is valid, else false</returns>
    public bool IsValid()
    {
        return Minimum.CompareTo(Maximum) <= 0;
    }

    public XmlSchema GetSchema() { return null; }

    public void ReadXml(XmlReader reader)
    {
        // start reading
        reader.MoveToContent();

        Type t = typeof(T);
        var min = reader["Minimum"];
        var max = reader["Maximum"];

        Minimum = (T)Convert.ChangeType(min, t);
        Maximum = (T)Convert.ChangeType(max, t);

        reader.Read();
    }

    public void WriteXml(XmlWriter writer)
    {
        writer.WriteAttributeString("Minimum", Minimum.ToString());
        writer.WriteAttributeString("Maximum", Maximum.ToString());
    }
}

但是当我想使用这个 class 如下...,

public Range<double> Whr;

我收到这个错误

严重性代码说明项目文件行抑制状态 错误 CS0315 类型 'double' 不能用作泛型类型或方法 'Range' 中的类型参数 'T'。没有从 'double' 到 'System.Runtime.Serialization.ISerializable' 的装箱转换。 XCLASS ...\ACLASS.cs 89 活动

我该如何解决这个错误?

我想你想要:

public class Range<T> : ISerializable where T : IComparable<T>

按照您现在的方式,T 必须实施 ISerializable。您希望 class 改为实施 ISerializable
