从JSON对象中删除特定属性

您可以先解析字符串：

var temp =  JArray.Parse(json);temp.Descendants()    .OfType<JProperty>()    .Where(attr => attr.Name.StartsWith("_umb_"))    .ToList() // you should call ToList because you're about to changing the result, which is not possible if it is IEnumerable    .ForEach(attr => attr.Remove()); // removing unwanted attributesjson = temp.ToString(); // backing result to json

更新 或：

result.Properties()    .Where(attr => attr.Name.StartsWith("_umb_"))    .ToList()    .ForEach(attr => attr.Remove());

更新＃2

您可以在

where

.Where(attr => attr.Name.StartsWith("_umb_") && some_other_condition)

要么

.Where(attr => attr.Name.StartsWith("_umb_") || some_other_condition)

或任何您需要的。
