Help with use of .NET Generics/Dictionary in replacing my Arrays
- by Rollo R
Hello, I have these code:
Mypage.cs
string[] strParameterName = new string[2] {"?FirstName", "?LastName"};
string[] strParameterValue = new string[2] {"Josef", "Stalin"};
MyConnection.MySqlLink(strConnection, strCommand, strParameterName, strParameterValue, dtTable);
Myclass.cs
public static void MySqlLink(string strConnection, string strCommand, string[] strParameterName, string[] strParameterValue, DataTable dtTable)
{
dtTable.Clear();
MySqlConnection MyConnection = new MySqlConnection(strConnection);
MySqlCommand MyCommand = new MySqlCommand(strCommand, MyConnection);
for (int i = 0; i < strParameterName.Length; i++)
{
MyCommand.Parameters.AddWithValue(strParameterName[i].ToString(), strParameterValue[i].ToString());
}
MySqlDataAdapter MyDataAdapter = new MySqlDataAdapter(MyCommand);
MyDataAdapter.Fill(dtTable);
}
And then my Sql Command will be something like "SELECT * FROM MyTable WHERE FirstName=?FirstName AND LastName=?LastName"
As you can see, I am using arrays for the Parameter Name and Parameter Value and they both have to "match" with each other and ofcourse the Sql Command.
Someone recommended to me that I use .NET "Dictionary" instead of arrays. Now I have never used that before. Can someone show me a relative example of how I am to use .NET Dictionary here?
