【问题描述】：

我尝试了多种配置，但无法将数据传递给控制器。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)
    { 
      ...
    }

这里是 ajax 请求以及一些示例 json 数据。尝试提交两个版本，但在到达控制器时继续为空。

var data = { "partsImport": [{ "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" }] };

//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" }] ;

$.ajax({
        url: "/purchasing/ImportPartsData",
        type: "POST",
        data: JSON.stringify(data),
        contentType: "application/json; charset=utf-8",
        dataType: 'json',
        success: function (response) {

        },
        error: function (xhr, errorType, exception) {

        },
    });

我认为最简单的方法是删除"partsImport":。

【解决方案1】：

删除{"partsImport":}。更改您的代码如下：

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：
