2つのメソッド間のあいまいさがC＃

Question

public double BAL_insert() 
{ 
    return dobj.DAL_insert(this); 
} 

public double DAL_insert(BAL_class bobj) 
{ 
    con = cobj.tierconnection(); 
    con.Open(); 
    query = "insert into Employeeinandout values(@prm_Name)"; 
    cmd = new SqlCommand(query, con); 
    cmd.Parameters.AddWithValue("@prm_Name", bobj.name); 
    double r = cmd.ExecuteNonQuery(); 
    con.Close(); 
    return r; 
} 

[これらの2つのメソッド間で曖昧になりました。どうすれば解決できますか？]

Answer 1

これを試してください。

public double DAL_insert(BAL_class bobj = null) 
    { 
     if(bobj == null) 
     { 
      bobj = this; 
     } 
     con = cobj.tierconnection(); 
     con.Open(); 
     query = "insert into Employeeinandout values(@prm_Name)"; 
     cmd = new SqlCommand(query, con); 
     cmd.Parameters.AddWithValue("@prm_Name", bobj.name); 
     double r = cmd.ExecuteNonQuery(); 
     con.Close(); 
     return r; 
    }
