如何将我已经保在excel的数据导入到LightningChart中，来展示我需要的内容?

something like this:

String[,] arr = new String[xlWorksheet.UsedRange.Rows.Count,xlWorksheet.UsedRange.Columns.Count];
for (int row = 1; row <= xlWorksheet.UsedRange.Rows.Count; ++row)
{
for (int col = 1; col <= xlWorksheet.UsedRange.Columns.Count; ++col)
{
arr[row,col] = valueArray[row, col].ToString();
}
}

You can also use Array.Copy like: https://social.msdn.microsoft.com/Forums/en-US/5d525b76-f5b6-4340-a899-c3c82570d2e1/is-there-a-twodimensional-arraycopy-method-?forum=netfxbcl
