IDbDataParameter参数转换的问题, 一直困惑.

[blackpipi]

Private Shared Function getSQLParameter(ByVal ParamArray commandParameters() As IDbDataParameter) As SqlParameter()
Dim i As Integer
Dim newParamter() As SqlParameter
If Not (commandParameters Is Nothing) Then
If commandParameters.Length > 0 Then
ReDim newParamter(commandParameters.Length - 1)
For i = 0 To commandParameters.Length - 1
newParamter(i) = CType(commandParameters(i), SqlParameter)
Next
End If
Else
newParamter = CType(Nothing, SqlParameter())
End If
Return newParamter
End Function

现在用C#写, 我想知道 CType(commandParameters(i), SqlParameter) 应该怎么写,谢谢!

反正现在这样是错的 newParamter[i]= (SqlParameter)commandParameters[i];

你可以用如下的写法:
newParamter(i) = (SqlParameter)commandParameters(i);

C#的数组是用[]的,不是()呀

用这个试试看:
SqlParameter [] newParamter = new SqlParameter[1];
newParamter[0] = new SqlParameter(commandParameters[i]);

参考这个：
public void CreateSqlParameter()
{
SqlParameter myParameter = new SqlParameter("@Description",SqlDbType.VarChar,11,ParameterDirection.Input,
true,0,0,"Description",DataRowVersion.Current,"garden hose");
myParameter.IsNullable = true;
}

唉,那不是很简单了嘛:
newParamter[i] = (SqlParameter)commandParameters[i];

[blackpipi]

newParamter[i] = (SqlParameter)commandParameters[i];

SqlParameter [] newParamter = new SqlParameter[1];
newParamter[0] = new SqlParameter(commandParameters[i]);

这些都不行呀
