Question

我想从视图模型中将存储过程调用到ActionResult中。

输入变量nGUID是一个字符串，KeepPersonID和dropPersonID都是十进制类型。当我尝试运行我的代码时出现错误'无法将类型十进制隐式转换为字符串' 这是我的代码。

调用过程MergeAuthIDs

public static void MergeAuthIDs(
OracleTransaction trans, decimal KeepPersonID, decimal dropPersonID)
{
  using (OracleCommand cm = new OracleCommand())
   {
     cm.Connection = trans.Connection;
     cm.Transaction = trans;
     cm.CommandText = "TheService.PKG#IDENTITIES.Merge_Auth_Ids";
     cm.CommandType = CommandType.StoredProcedure;
     cm.AddToStatementCache = true;

     OracleParameter param = cm.Paramaters.Add("P_KEEP_PERSON_ID", OracleDBType.Decimal, Paremeter.Direction.Input);
     param.Value = keepPersonID;

     param = cm.Paramaters.Add("P_DROP_PERSON_ID", OracleDBType.Decimal, Paremeter.Direction.Input);
     param.Value = dropPersonID;

     cm.ExecuteNonQuery();

IdentityConfirmed ViewModel控制器

[httpPost]
public ActionResult IdentityConfirmed(FormCollection collection)
{
    Guid request = new Guid(collection["ciGUID"]);

    dsSession.SECURE_REQUESTSRow secureRequest;

    using (OracleConnection cn = new OracleConnection (OracleConnectionManager.GetProxyServiceConnetionString()))
    {
        cn.Open();
        using (OracleTransaction trans = cn.BeginTransaction())
        {
              using (Data.dsSessionTableAdapters.SECURE_REQUESTSTableAdapter ta = new Data.dsSessionTableAdapters.SECURE_REQUESTSTableAdapter();
              {
                 typedDatasetFiller.ApplyConnection(ta, cn);
                 secureRequest = ta.GetDataBySecureGUID(request.ToByteArray())[0];
              }
              decimal KeepPersonID = SessionManager.PersonIdentity.PERSON_ID;
              decimal dropPersonID = secureRequest.REQUESTER_PERSON_ID;

              Support.MergeAuthIDs(trans, KeepPersonID, dropPersonID);
              trans.Commit();
        }
    }
retrun View("IdentityConfirmed", vm);
}

Answer 1

它希望是一个字符串。检查数据库中的列类型并将其更改为十进制。

Answer 2

这是答案，我忘了将变量dropPersonID设置为正确的值。

     using (Data.dsSessionTableAdapters.SECURE_REQUESTSTableAdapter ta = new  Data.dsSessionTableAdapters.SECURE_REQUESTSTableAdapter();
          {
             typedDatasetFiller.ApplyConnection(ta, cn);
             secureRequest = ta.GetDataBySecureGUID(request.ToByteArray())[0];
          }
          decimal KeepPersonID = SessionManager.PersonIdentity.PERSON_ID;
          decimal dropPersonID = secureRequest.REQUESTER_PERSON_ID;

          Support.MergeAuthIDs(trans, KeepPersonID, dropPersonID);

不能隐式将十进制类型转换为字符串
