无法使用YamlDotNet序列化KeyValuePair(Unable to serialize a KeyValuePair with YamlDotNet)

无法使用YamlDotNet序列化KeyValuePair(Unable to serialize a KeyValuePair with YamlDotNet)

我正在编写一个简单的类来序列化我的IConfiguration接口，该接口具有以下方法

IEnumerable<KeyValuePair<string, object>> GetAllProperties();

在我的班上，我有一个方法

public void WriteConfiguration(IConfiguration data, Stream stream) { new Serializer().Serialize(new StreamWriter(stream), data.GetAllProperties()); }

但是Serializer不会向流写入任何内容。 在某处我读到KeyValuePair不可序列化，但现在不再是这种情况了（它在.NET 2.0中）

我尝试首先将IEnumerable转换为List （使用.ToList() ），但没有任何改变。 然后我尝试创建一个使用的类而不是KeyValuePair ：

[Serializable] private class Pair<TKey, TValue> { public Pair() { } public Pair(TKey key, TValue value) { Key = key; Value = value; } public TKey Key { get; set; } public TValue Value { get; set; } }

但它仍然无效。

I'm writing a simple class that serializes my IConfiguration interface which has the following method

IEnumerable<KeyValuePair<string, object>> GetAllProperties();

In my class I have a method

public void WriteConfiguration(IConfiguration data, Stream stream) { new Serializer().Serialize(new StreamWriter(stream), data.GetAllProperties()); }

But the Serializer doesn't write anything to the stream. Somewhere I read that KeyValuePair is not serializable, but this isn't the case anymore now (it was in .NET 2.0)

I tried first converting the IEnumerable to a List (using .ToList()), but nothing's changed. Then I tried creating a class to use instead of KeyValuePair:

[Serializable] private class Pair<TKey, TValue> { public Pair() { } public Pair(TKey key, TValue value) { Key = key; Value = value; } public TKey Key { get; set; } public TValue Value { get; set; } }

But it still doesn't work.

最满意答案

这是因为您没有丢弃StreamWriter ，因此它不会刷新到流。 尝试将其放入using块中：

public void WriteConfiguration(IConfiguration data, Stream stream) { using (var writer = new StreamWriter(stream)) { new Serializer().Serialize(writer, data.GetAllProperties()); } }

注意：默认情况下，处理StreamWriter也会关闭基础流。 如果要保持打开状态，请使用带有leaveOpen参数的StreamWriter构造函数重载，并leaveOpen参数传递true。

This is because you don't dispose the StreamWriter, so it isn't flushed to the stream. Try putting it in a using block:

public void WriteConfiguration(IConfiguration data, Stream stream) { using (var writer = new StreamWriter(stream)) { new Serializer().Serialize(writer, data.GetAllProperties()); } }

Note: by default, disposing the StreamWriter will also close the underlying stream. If you want to keep it open, use the StreamWriter constructor overload that takes a leaveOpen parameter, and pass true for this parameter.
