asp.net C＃中的“ ArrayOfKeyValueOfstringstringKeyValueOfstringstring []）'有一些无效的参数”

Question

在下面的代码中，我有一个wcf方法和void方法。 当我执行它时，它会引发错误

“错误170'WebApp.MasterBiz.MastersClient.UpdateOtherExpenseCost（WebApp.MasterBiz.ArrayOfKeyValueOfstringstringKeyValueOfstringstring []）的最佳重载方法匹配具有一些无效的参数”

请帮我解决问题。

无效方法：

Dictionary<string, string> GRNCostInVals = new Dictionary<string, string>();
GRNCostInVals.Add("GRNID", hidGoodsReceivedNoteID.Value.ToString());
GRNCostInVals.Add("LoadingCost", txtLoadingCost.Value.ToString());
GRNCostInVals.Add("UnloadingCost", txtUnloadingCost.Value.ToString());
GRNCostInVals.Add("InsuranseCost", txtInsuranseCost.Value.ToString());
GRNCostInVals.Add("MiscCost", txtMiscCost.Value.ToString());
GRNCostInVals.Add("MiscDescription", txtMiscDesc.Value.ToString());
GRNCostInVals.Add("TransporterBillNo", txtTransporterBillNo.Value.ToString());
GRNCostInVals.Add("TransporterBillDate", txtTransporterBillDate.Value.ToString());
GRNCostInVals.Add("FreightCharges", txtTranspotationCost.Value.ToString());

objCost.UpdateOtherExpenseCost(GRNCostInVals);  

WCF方法：

public int UpdateOtherExpenseCost(Dictionary<string, string> objCost)
{
    try
    {
        SqlParameter[] SqlParam = new SqlParameter[9];

        SqlParam[0] = new SqlParameter("@i_GRNID", SqlDbType.Int);
        SqlParam[0].Value = objCost["GRNID"];               

        SqlParam[1] = new SqlParameter("@nu_LoadingCost", SqlDbType.Float);
        SqlParam[1].Value = float.Parse(objCost["LoadingCost"]);

        SqlParam[2] = new SqlParameter("@nu_UnloadingCost", SqlDbType.Float);
        SqlParam[2].Value = float.Parse(objCost["UnloadingCost"]);

        SqlParam[3] = new SqlParameter("@nu_MiscCost", SqlDbType.Float);
        SqlParam[3].Value = float.Parse(objCost["MiscCost"]);

        SqlParam[4] = new SqlParameter("@vc_MiscDesc", SqlDbType.VarChar, 200);
        SqlParam[4].Value = objCost["MiscDescription"];

        SqlParam[5] = new SqlParameter("@nu_InsuranseCost", SqlDbType.Float);
        SqlParam[5].Value = float.Parse(objCost["InsuranseCost"]);

        SqlParam[6] = new SqlParameter("@vc_TransporterBillNo", SqlDbType.VarChar, 50);
        SqlParam[6].Value = objCost["TransporterBillNo"];

        SqlParam[7] = new SqlParameter("@dt_TransporterBillDate", SqlDbType.DateTime);
        SqlParam[7].Value = DateTime.Parse(objCost["TransporterBillDate"]);

        SqlParam[8] = new SqlParameter("@nu_TransportationCost", SqlDbType.Float);
        SqlParam[8].Value = float.Parse(objCost["FreightCharges"]);

        SqlHelper SqlHelp = new SqlHelper();
        return SqlHelp.ExecuteNonQuery(SqlParam, "Sp_UpdateOtherExpenseCost");


    }
    catch (Exception ex)
    {
        GmasSupportException GmasSupportEx = new GmasSupportException();
        GmasSupportEx.ExceptionType = ex.GetType().ToString();
        GmasSupportEx.Message = ex.Message.ToString();
        if (ex.InnerException != null)
            GmasSupportEx.InnerExceptionMessage = ex.InnerException.Message;

        throw new FaultException<GmasSupportException>(GmasSupportEx, new FaultReason(ex.Message.ToString()));
    }
}

看起来问题在于，当您导入服务引用时，映射词典时出了点问题。

或者，您可能已将其添加为Web参考而不是新的Service Reference 。

您可以尝试再次添加引用，并验证System.Collections.Generic.Dictionary 是使用的Dictionary集合类型，并且Collection类型是 System.Collection.Generic.List 。

除此之外，您可以提供代理正在等待的确切对象，因此您的代码将如下所示：

using WebApp.MasterBiz;
//...
var GRNCostInVals = new ArrayOfKeyValueOfstringstringKeyValueOfstringstring[2];

GRNCostInVals[0] = new ArrayOfKeyValueOfstringstringKeyValueOfstringstring();
GRNCostInVals[0].Key = "GRNID";
GRNCostInVals[0].Value = hidGoodsReceivedNoteID.Value.ToString();

GRNCostInVals[1] = new ArrayOfKeyValueOfstringstringKeyValueOfstringstring();
GRNCostInVals[1].Key = "LoadingCost"
GRNCostInVals[1] = txtLoadingCost.Value.ToString();
//...
