Streamreader 和 "Index was outside the bounds of the array" 错误

Question

我没有写入任何数组长度，但是当我尝试读取 .csv 文件时，出现 "Index was outside the bounds of the array" 错误。 .csv 文件大约有 1 000 000 行。有人可以修复此代码吗？

.csv 文件行如下。

0000000,26.0000000000000,38.0000000000000,30.01.2017,0,0,0,,,0,0,,0,,0,0,0,0

string[] read;
char[] seperators = { ',' };


        try
        {
            Image img = Image.FromFile(txtFilePath.Text); 
            Graphics g = Graphics.FromImage(img);
            pictureBox1.Image = img;
            pictureBox1.SizeMode = PictureBoxSizeMode.StretchImage;

            StreamReader sr = new StreamReader(txtFile2Path.Text);

            string data;

            while ((data=sr.ReadLine()) !=null)
            {
                read = data.Split(seperators, StringSplitOptions.None);

                float x = float.Parse(read[1]);
                float y = float.Parse(read[2]);
                string z = read[10];
            }
        }


        catch (Exception ex)
        {
            MessageBox.Show(ex.Message);
        }

只是为了向最终出现在这里的任何人澄清答案..

        while ((data=sr.ReadLine()) !=null)
        {
            read = data.Split(seperators, StringSplitOptions.None);
            if (read.Length >= 11)
            {
                float x = float.Parse(read[1]);
                float y = float.Parse(read[2]);
                string z = read[10];
            }
        }

访问可能不是所需长度的数组时，请先进行检查。

仅当一行代码试图访问数组中不存在的项目 (N-1) 时才会抛出 Index was outside the bounds of the array 异常 - 由于数组少于 (N)项目
