我必须转换System.Collections.Generic.IDictionary<string, decimal>为System.Collections.Generic.Dictionary<string, decimal>,而我不能.我尝试了ToDictionary方法,无法指定正确的参数.
我尝试过以下方法:
// my dictionary is PlannedSurfaces (of type IDictionary<string, decimal>)
blabla.ToDictionary<string, decimal>(localConstruction.PlannedSurfaces)
在我的项目中,我必须以任何格式(*.png,*.jpg,*.bmp等)比较两个图像,并返回百分比的相似率.
有没有人这样做？
如果有,怎么样？

示例(禁用删除计数):
string1:你好吗？
string2:oyu怎么样？
距离: 1(换位,4次删除不计算)
这是算法:
public static int DamerauLevenshteinDistance(string string1, string string2, int threshold)
{
// Return trivial case - where they are equal
if (string1.Equals(string2))
return 0;
// Return trivial case - where one is empty
if (String.IsNullOrEmpty(string1) || String.IsNullOrEmpty(string2))
return (string1 ?? "").Length + (string2 ?? "").Length;
// Ensure string2 (inner cycle) is longer_transpositionRow
if (string1.Length > string2.Length)
{
var tmp = string1;
string1 = string2;
string2 = tmp;
}
// Return …我想使用带有用户名/密码身份验证和ssl的传输安全模式,它适用于Windows身份验证:
<transport clientCredentialType="Windows"/>
我在msdn上发现了一篇文章解释了如何使用传输安全模式进行用户名/密码身份验证,但需要自定义http模块.我感兴趣的是为什么没有默认安全模式,如:
<transport clientCredentialType="Username"/>
如果我需要用户名/密码验证,我可以使用消息安全模式,但如果所有站点都使用https/ssl进行身份验证,那么在wcf中这样做应该不会有问题.
