| Name | Overloads | Summary |
|---|---|---|
| Evaluate | 1 | 两个字符串之间是通过单词的排布的相似度来比较相似度的 |
| LevenshteinEvaluate | 1 | 计算字符串，这个是直接通过计算字符而非像Evaluations.Evaluate())方法之中计算单词的 |
| TokenOrders | 2 | 以s1为准则，将s2进行比较，返回s2之中的单词在s1之中的排列顺序 |
| IsOrdered | 2 | |
| LevenshteinOrder | 1 | Make text similariy sort in desc order |
| StringSelection | 1 | Get most similar string from the given collection |
| LevenshteinOrder | 1 |

strlen_diff | Boolean | - |
Returns
a sort collection result by the text similarity measurement. this result collection may has elements number less than the input collection elements number.
StringSelection(
String, IEnumerable(Of String), Double, Boolean, Boolean)Get most similar string from the given collection
