C# DevExpress gridview 字符串尾部带数字如何排序

我们经常遇到这样的问题，字符串尾部带数字，如何正确排序;

首先设置GridView ,Columns 的相关列，设置属性中，SortMode为Custom

解决思路，把字符串尾缀数字，分离出来。先比较去除尾部数字的字符串，再比较尾部数字位。

gridView.CustomColumnSort += GridView_CustomColumnSort;

private void GridView_CustomColumnSort(object sender, DevExpress.XtraGrid.Views.Base.CustomColumnSortEventArgs e)
{
    if (e.Column == gridColumn)
    {
        string value1 = e.Value1.ToString();
        string value2 = e.Value2.ToString();
        var cc1 = GetNumberIndex(value1);
        var cc2 = GetNumberIndex(value2);
        if (cc1 > -1 && cc2 > -1)
        {
            string zm1 = value1.Substring(0, cc1);
            string zm2 = value2.Substring(0, cc2);
            if (zm1 == zm2)
            {
                string nb1 = value1.Substring(cc1);
                string nb2 = value2.Substring(cc2);
                decimal.TryParse(nb1, out decimal dec1);
                decimal.TryParse(nb2, out decimal dec2);
                int result = Comparer<decimal>.Default.Compare
                            (dec1, dec2);
                e.Result = result;
                e.Handled = true;
            }
        }
    }
}

private int GetNumberIndex(string value)
{
    int v = -1;
    if (value != null && value.Length > 1)
    {
        int i = 0;
        for (; i < value.Length; i++)
        {
            if (char.IsNumber(value[i]))
            {
                if (i != 0)
                {
                    v = i;
                }
                break;
            }
        }
    }
    return v;
}
