我在以下代码中收到此错误，该代码基本上会启动DROP DATABASE IF EXISTS VESSELS;

请求
POST
ABC.ascx var ABCid = $(aTag).data('id');
$.ajax({
type: "POST",
url: "WebMethods.aspx/Delete_Local_ABC",
data: "{'id':'" + ABCid + "'}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: successdelete_ABC,
error: Errordelete_ABC
});
}
WebMethods.aspx.cs我在[WebMethod]
public static int Delete_Local_ABC(string id)
{
ABC objABC = new ABC();
objABC.ABC_ID = Convert.ToInt32(id);
// call business manager
try
{
BusinessManager businessManager = new BusinessManager();
businessManager.ManageABC(objABC, OperationTypes.Validate);
return 1;
}
catch (Exception ex)
{
throw ex;
}
}
BusinessManager.cs和....
case OperationTypes.Validate:
obj.deleteLocalABC();
break;
...
ABC.cs我尝试过在线提供的所有解决方案但没有任何效果。此代码与public bool deleteLocalABC()
{
string query = "DELETE FROM TBL_ABC WHERE ABC_ID ='" + this.ABC_ID + "'";
_dbManager.executeQuery(query);
return true;
}
完美匹配，但不适用于主要部署。
答案 0 :(得分：1)
使用
[WebMethod, ScriptMethod(ResponseFormat = ResponseFormat.Json, UseHttpGet = false)]
而不只是[WebMethod]。
我希望你的方法在添加之后能正常工作。
