查询参数的问题

Question

我遇到麻烦将参数传递给查询会引发此异常

参数化查询'（@IdIndicador int）INSERT INTO [AtentoMIG]。[dbo]。[Indicador]（[Nom'期望参数'@IdIndicador'，未提供。 < / p>

这是我的代码

_sqlCommand = new SqlCommand
              ("INSERT INTO [AtentoMIG].[dbo].[Indicator]"                      
                  + "([Name]"
                  + ",[Descripction])"
                  + "VALUES"
                  + "('" + data[0] + "'"
                  + ",'" + data[13] + "') SET @IdIndicador = SCOPE_IDENTITY()", _sqlConexion);

SqlParameter idIndicador = new SqlParameter("@IdIndicador", SqlDbType.Int);
_sqlCommand.Parameters.Add(idIndicador);
_sqlCommand.Connection.Open();
_sqlCommand.ExecuteNonQuery();
int id = (int)idIndicador.Value;

_sqlConexion.Close();
return true;

为什么我做错了？对我来说，代码看起来不错

You forgot to supply the direction of the SqlParameter。尝试添加：

SqlParameter idIndicador = new SqlParameter("@IdIndicador", SqlDbType.Int);
idIndicator.Direction = ParameterDirection.Output;
// ...
