看起来您需要带输出参数的存储过程

Looks like you need stored procedure with output parameter

int errorId = 0;

using(SqlConnection sqlConnection = new SqlConnection(connectionString))
{
    using(SqlCommand cmd = new SqlCommand("YourStoredProcedureName", sqlConnection))
    {
    cmd.CommandType=CommandType.StoredProcedure;
    SqlParameter parm=new SqlParameter("@username", SqlDbType.VarChar); 
    parm.Value="mshiyam";
    parm.Direction =ParameterDirection.Input ; 
    cmd.Parameters.Add(parm); 

    SqlParameter parm2=new SqlParameter("@path",SqlDbType.VarChar); 
    parm2.value = "Some Path";
    parm2.Direction=ParameterDirection.Output;
    cmd.Parameters.Add(parm2); 


    SqlParameter parm3 = new SqlParameter("@errorId",SqlDbType.Int);
    parm3.Direction=ParameterDirection.Output; 
    cmd.Parameters.Add(parm3); 

    sqlConnection.Open(); 
    sqlConnection.ExecuteNonQuery();

    errorId = cmd.Parameters["@errorId"].Value; //This will 1 or 0
   }

}
