有没有办法像这样过滤 C# DataView？

Question

我正在用 c# 在 BindingSource 中编写一些用于过滤数据的代码。

在DataTable中，我有一列，数据是这样的，

coding is very good

我想在每个空 space 之后过滤字符串中的数据，就像我的例子，

var ss = "coding is      ery"; 
var s = ss.Split(" ".ToCharArray(), StringSplitOptions.RemoveEmptyEntries);

var filter = ColumnName + " like \'%" + s[0] + "%\' ";

        for (int i = 1; i < s.Length; i++)
        {
            filter = filter +  "AND " + ColumnName + " like \'%" + s[i] + "%\' ";
        }

BindingSource.Filter = filter;

这里的问题是我会得到所有的数据（编码很好）。当单词不是以正确的字母开头时，我不想获取数据。例如，

coding is ery.

我想成为

"coding very is" or "is very coding".

我想要正确的起始字母，但单词的位置无关紧要。

有人知道怎么做吗？

您需要这样检查：

var filter = "(" + columnName
    + " like \'" + s[0] + "%\' "          // first word
    + " OR like \'% " + s[0] + "%\' )";   //in a sentence

for (int i = 1; i < s.Length; i++)
{
    filter += "AND " + "(" + columnName
    + " like \'" + s[i] + "%\' "          // first word
    + " OR like \'% " + s[i] + "%\' )";   //in a sentence
}
