c# – 从电子表格中读取行数据

我遇到的两个问题是

>我无法看到获得行
>我无法看到获得列索引
这是我的代码

public void ParseExcelFile(FileInfo file) 
{
    using (SLDocument sl = new SLDocument())
    {
        FileStream fs = new FileStream(file.FullName,FileMode.Open);

        MemoryStream msFirstPass = new MemoryStream();
        SLDocument sheet1 = new SLDocument(fs,"Sheet1");


        // There is no way that I can see to get the Rows
        foreach(var row in sheet1.Rows)
        {
            foreach(SLCell c in row)
            {
                // There is no way that I can see to get the Column Index
                switch(c.Column )
                {
                    case 1:
                        //Handle data if cell is Column 1
                        break;
                    case 2:
                        //Handle data if cell is Column 2
                        break;
                    case 3:
                        //Handle data if cell is Column 3
                        break;
                }
            }
        }
