如何将datagridview数据传输到锯齿状数组 [英] How can I transport datagridview data to jagged array

问题描述

我正在尝试将datagridview数据传输到锯齿状阵列但出于某种原因但我无法成功



错误是：

Hi, I am trying to transport datagridview data to jagged array for some reason but I couldn't succeed

the error is:

An unhandled exception of type 'System.FormatException' occurred in mscorlib.dll

Additional information: The input line was not in the correct format.

我的datagridview数据是这样的;

my datagridview data is like;

|0.35|1.58|0.82|1.78|0.85|1.55|1|0|0|}

我的尝试：

What I have tried:

string linex= "";
string[] correction= null;
for (int i=0;i<= rowcount-1;i++)
{
                
    for (int j=0;j<= colmcount-1;j++)
    {
        linex= linex.ToString()+" " + dataGridView1.Rows[i].Cells[j].Value.ToString();
    }
    correction= linex.Split(',');
    rowdataexample[i] = new double[columncnt];
    for (int k = 0; k <= colmcount-1; k++)
    {
        rowdataexample[i][k] = double.Parse(correction[k]);

    }
    correction= null;
    linex= "";
}

推荐答案

为此添加逗号

add comma to this

linex= linex.ToString()+"," + dataGridView1.Rows[i].Cells[j].Value.ToString();

注意：

使用 Double.TryParse Method（System） [ ^ ]将字符串转换为double

使用 String.Trim方法（系统） [ ^ ]以避免开始时不需要的空间字符串的结尾。

Note:
use Double.TryParse Method (System)[^] for converting string to double
use String.Trim Method (System)[^] to avoid unwanted space in the beginning and end of the string.
