Trouble passing parameters to array of sqlparameters

I have this code

Code:

---

    Public Function ExecuteDataReaderSP( _
            ByVal storedProcedureName As String, _
            ByVal ParamArray arrParam() As SqlParameter) As SqlDataReader

        Dim reader As SqlDataReader

        ' Open the connection
        If m_cn.State <> ConnectionState.Open Then m_cn.Open()

        ' Define the command
        Dim cmd As New SqlCommand
        cmd.Connection = m_cn
        cmd.CommandType = CommandType.StoredProcedure
        cmd.CommandText = storedProcedureName

        ' Handle the parameters
        If arrParam IsNot Nothing Then
            For Each param As SqlParameter In arrParam
                cmd.Parameters.Add(param)
            Next
        End If

        ' Execute the reader
        reader = cmd.ExecuteReader(CommandBehavior.CloseConnection)

        Return reader
    End Function

---

how I pass parameters
im using ExecuteDataReaderSP("Name_Of_SP",parameter1,parameter2)

I try various ways to pass the parameters, every time it return a different error.
How is the correct way to pass those parameters?

thanks!

Sorry, but I have this in VB6, but it should help:

Code:

---

Option Explicit

Private Sub Form_Load()
  ParamAdd
End Sub

Sub ParamAdd()
Dim cmdSQLInsert As ADODB.Command
Set cmdSQLInsert = New ADODB.Command

'Create the query
cmdSQLInsert.CommandText = "Insert Into Table1(ID, NAME, AGE) Values(?,?,?)"
cmdSQLInsert.CommandType = adCmdText
cmdSQLInsert.Prepared = True

'Create the parameters
'in this case we will create three parameters
'-----Param 1 (for Field ID)-------------
Dim gParam As ADODB.Parameter
Set gParam = New ADODB.Parameter
With gParam
    .Name = "ID"
    .Direction = adParamInput
    .Type = adChar
    .Size = 10
    .Value = "xxxxxxxxxx"
End With
cmdSQLInsert.Parameters.Append gParam

'-----Param 2 (for Field Name)-------------
Set gParam = Nothing
Set gParam = New ADODB.Parameter
With gParam
    .Name = "NAME"
    .Direction = adParamInput
    .Type = adVarChar
    .Size = 50
    .Value = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
End With
cmdSQLInsert.Parameters.Append gParam

'-----Param 3 (for Field AGE)-------------
Set gParam = Nothing
Set gParam = New ADODB.Parameter
With gParam
    .Name = "AGE"
    .Direction = adParamInput
    .Type = adChar
    .Size = 2
    .Value = "xx"
End With
cmdSQLInsert.Parameters.Append gParam

'Set the connection property of the command object
Set cmdSQLInsert.ActiveConnection = mySQLConnection
'pass the values that need to be inserted to specific parameters that we created above
cmdSQLInsert("ID") = txtID.Text
cmdSQLInsert("NAME") = txtID.Text
cmdSQLInsert("AGE") = txtAge.Text

'Execute the command
cmdSQLInsert.Execute
End Sub
