C# 将Application Insights查询API调用结果转换为DataTable
我正在使用Application Insight记录CustomEvent。我想通过代码(c#)查询它。我发现了如何使用,以及如何使用GET/Query运行查询并获得JSON结果 当我查看JSON字符串时,它看起来是在定义一个表:C# 将Application Insights查询API调用结果转换为DataTable,c#,json,azure,datatable,azure-application-insights,C#,Json,Azure,Datatable,Azure Application Insights,我正在使用Application Insight记录CustomEvent。我想通过代码(c#)查询它。我发现了如何使用,以及如何使用GET/Query运行查询并获得JSON结果 当我查看JSON字符串时,它看起来是在定义一个表: { "tables": [ { "name": "PrimaryResult", "columns": [ { "name": "times
{
"tables": [

"2019-01-10T16:09:44.2443658Z",
"zzzz",
"customEvent",
"{\"Application\":\"LogClient-IntegrationTests\",\"EventType\":\"Action\"}",
因此,我想知道是否存在将结果转换为数据表的方法?很难或不可能转换为
数据表
,因为结果中的某些值是动态类型(如自定义维度
和自定义度量
)
我使用字典来存储重构后的结果(对于动态类型,如customDimensions
,我只是将其视为一个字符串进行测试。如果您想继续此操作,可以为此使用更复杂的字典类型)
