包含 “é 时，将 Json 反序列化为对象时出错è à”人物

我尝试使用 DataContractJsonSerializer 将 JSON 字符串反序列化为对象。一切正常，直到 JSON 字符串包含一些法语字符，例如 é è à。它会抛出异常：

反序列化 ** 类型的对象时出错。预期为标记“”，但找到了“é”。

有人知道如何解决它吗？

{ "features": [ { "id": "0c50cdc5-da97-45be-aad2-ad1433d8e285LastEditedFeature", "wkt": "", "fieldValues": [ { "Key": "formeID", "Value": "1" }, { "Key": "calqueID", "Value": "1" }, { "Key": "featureID", "Value": "0c50cdc5-da97-45be-aad2-ad1433d8e285" }, { "Key": "Name", "Value": "ABCDé" } ] } ] }

恐怕它是由“ABCDé”字符串中的é引起的。

I tried using DataContractJsonSerializer to deserialize the JSON string to object. All works fine until the JSON string contains some French characters, such as é è à. It will throw the exception:

There was an error deserializing the object of type **. The token '"' was expected but found 'é'.

Is there anybody know to resolve it?

{ "features": [ { "id": "0c50cdc5-da97-45be-aad2-ad1433d8e285LastEditedFeature", "wkt": "", "fieldValues": [ { "Key": "formeID", "Value": "1" }, { "Key": "calqueID", "Value": "1" }, { "Key": "featureID", "Value": "0c50cdc5-da97-45be-aad2-ad1433d8e285" }, { "Key": "Name", "Value": "ABCDé" } ] } ] }

I'm afraid that maybe it's caused by the é in "ABCDé" string.

该错误似乎表明您在字符串末尾缺少引号？

为了更好地帮助我们，您可以发布有效和无效的 JSON 吗？

除了已接受的答案之外，.net-3.5 JSON 实现。 .net-3.5 会导致如下所示的证明字符串出现此错误。但是，如果您将项目切换到 .net -4.0 或更高，问题立即消失。

string proofString = "";
for (int i = 1; i <= 0xffff; i++) {
    if (i >= 0xd800 && i < 0xe000) continue; // skip code points not belonging to UTF-8
    proofString += Strings.ChrW(i);
}

Besides the accepted answer, there seems to be an issue in .net-3.5 JSON implementation. Plain UTF-8 JSON serialization and deserialization in .net-3.5 leads to this error on proof-string shown below. But if you switch the project to .net-4.0 or higher, the issue immediately disappears.

string proofString = "";
for (int i = 1; i <= 0xffff; i++) {
    if (i >= 0xd800 && i < 0xe000) continue; // skip code points not belonging to UTF-8
    proofString += Strings.ChrW(i);
}
