我正在尝试创建一个模式,以确保外部提供的JSON具有以下形式:
{ Username: "Aaron" }
现在,我正在通过以下方式在C#中创建一个Newtonsoft JSchema对象:
var sch = new JSchema()
{
Type = JSchemaType.Object,
AllowAdditionalProperties = false,
Properties =
{
{
"Username",
new JSchema() { Type = JSchemaType.String }
}
}
};
这很接近,但不需要存在Username属性。我尝试了以下内容:
var sch = new JSchema()
{
Type = JSchemaType.Object,
AllowAdditionalProperties = false,
Properties =
{
{
"Username",
new JSchema() { Type = JSchemaType.String }
}
},
Required = new List<string> { "Username" }
};
但我明白了:
Error CS0200 Property or indexer 'JSchema.Required' cannot be assigned to -- it is read only
事实上,文档指出Required属性是只读的:
https://www.newtonsoft.com/jsonschema/help/html/P_Newtonsoft_Json_Schema_JSchema_Required.htm
我错过了什么吗?为什么Required属性是只读的?我如何要求存在用户名?

您无法设置Required
(只是get
)而不是:
var sch = new JSchema()
{
Type = JSchemaType.Object,
AllowAdditionalProperties = false,
Properties =
{
{
"Username",
new JSchema() { Type = JSchemaType.String }
}
},
};
sch.Required.Add("Username");

您可以将C# Collection Initialization syntax与只读列表属性like so结合使用:
var sch = new JSchema()
{
Type = JSchemaType.Object,
AllowAdditionalProperties = false,
Properties =
{
{
"Username",
new JSchema() { Type = JSchemaType.String }
}
},
Required = // <-- here!
{
"Username"
}
};
