.Net核心AJAX Post Null

我尝试了各种配置，但无法将数据传递到控制器。我错过了什么

public class PartsImport
{
    public string companyID { get; set; }
    public string partsCategoryID { get; set; }
    public string subCategoryID { get; set; }
    public string partNumber { get; set; }
    public string name { get; set; }
    public string description { get; set; }
    public string description2 { get; set; }
    public string quantity { get; set; }
    public string cost { get; set; }
    public string price { get; set; }
    public string vendorID { get; set; }
    public string mfg { get; set; }
    public string companyLocationID { get; set; }
}

控制器。此时partsImport为空

    [Authorize(Roles = "Admin")]
    [HttpPost]
    public async Task<IActionResult> ImportPartsData([FromBody] IEnumerable<PartsImport> partsImport)
    { 
      ...
    }

删除

{“partsImport”：}

。按如下方式更改代码：

var data = [{ "companyID": "57", "partsCategoryID": "205", "subCategoryID": "", "partNumber": "1", "name": "PVC Conduit 1/2 inch by 10 Feet", "description": "1/2 inch", "description2": "", "quantity": "1", "cost": "2.40", "price": "3.10", "vendorID": "", "mfg": "", "companyLocationID": "156" }, 
            { "companyID": "57", "partsCategoryID": "205", "subCategoryID": "", "partNumber": "2", "name": "PVC Conduit 3/4 inch by 10 Feet", "description": "3/4 inch", "description2": "", "quantity": "1", "cost": "3.03", "price": "3.91", "vendorID": "", "mfg": "", "companyLocationID": "156" }
           ];

结果:

---

最简单的方法是删除

“partsImport”：

我想。

var data = [{ "companyID": "57", "partsCategoryID": "205", "subCategoryID": "", "partNumber": "1", "name": "PVC Conduit 1/2 inch by 10 Feet", "description": "1/2 inch", "description2": "", "quantity": "1", "cost": "2.40", "price": "3.10", "vendorID": "", "mfg": "", "companyLocationID": "156" }, 
            { "companyID": "57", "partsCategoryID": "205", "subCategoryID": "", "partNumber": "2", "name": "PVC Conduit 3/4 inch by 10 Feet", "description": "3/4 inch", "description2": "", "quantity": "1", "cost": "3.03", "price": "3.91", "vendorID": "", "mfg": "", "companyLocationID": "156" }
           ];
