Question

Okay I’m trying to move from VB to C# with mixed success.

I’m getting the following errors:

1. The best overloaded method match for
   ‘_DataInteraction.stdReturnDataTable(string, ref
   System.Collections.Generic.List,
   string)’ has some invalid arguments

2. Argument 2 must be passed with the ‘ref’ keyword

Both referencing: the myParamList noted with ** in

I have this code in C#

{

    List<SqlParameter> myParamList = new List<SqlParameter>();
    SqlParameter myParam = default(SqlParameter);

    myParam = new SqlParameter("@sAMAccountName", SqlDbType.VarChar);
    myParam.Value = ID;
    myParamList.Add(myParam);

    **dt = _DI.stdReturnDataTable("cit_ResolveUser", myParamList, "x");**

    return dt;
}

Now the code for stdReturnDataTable (just the top part which accepts the arguments)

public static DataSet stdReturnDataset(string procedureName, ref List<SqlParameter> myParameters, string db)
    {
       //code
    }

Answer 1

As the error message says, you should pass the argument with the ref keyword:

dt = DataInteraction.stdReturnDataTable("cit_ResolveUser", ref myParamList, "ParabisIntranet");

Also, as per your comment, it’s a static method, you can not call it through an instance variable. Instead you need to qualify it using the typename.

But I suspect the ref keyword is actually not needed here, you can probably just remove it from the method signature.

public static DataSet stdReturnDataset(string procedureName, 
                                       List<SqlParameter> myParameters, 
                                       string db)
