Question

我想从csv文件（blob）中导入Collection（Edm.GeographyPoint）类型的字段中的多个地理点。我找不到用于csv文件的正确语法-索引器总是抱怨说，将字符串导入到地理字段中是无效的。

索引单个Edm.GeographyPoint可以正常工作。

实际CSV （不起作用）如下所示：

"product","vendor","coordinates"
"Coca Cola 0.5l","Billa","[{ ""type"": ""Point"", ""coordinates"": [48.4547895 16.5897845]},{ ""type"": ""Point"", ""coordinates"": [48.4567815 16.6854853]},{ ""type"": ""Point"", ""coordinates"": [48.8794568 16.5687491]}]"

我正在寻找CSV中此集合的正确格式/语法。

您缺少将x和y坐标分开的逗号。尝试像这样构造CSV：

"product","vendor","coordinates"
"Coca Cola 0.5l","Billa","[{ ""type"": ""Point"", ""coordinates"": [48.4547895,16.5897845]},{ ""type"": ""Point"", ""coordinates"": [48.4567815,16.6854853]},{ ""type"": ""Point"", ""coordinates"": [48.8794568,16.5687491]}]"
