尽管两个字符串相同，但C#.net核心不能标识相同 [英] Eventhough two strings are same , C# .net core is not identifying as same

问题描述

我在asp.net核心中发现了此问题.我有两个字母数字字符串，全部为大写，中间或结尾都没有空格.

I found this issue in asp.net core. I have two strings alpha numeric, all upper cases, and no spaces either in the middle or ends.

我从 appsettings.json 中获得一个字符串，而其他则在本地分配.当我比较这两个字符串时，应用程序显示它们不相同.

I am getting one string from appsettings.json and other assigning locally. When I compare those two strings, the application is showing they are not the same.

string stringFromAppSetting = Configuration.GetValue<string>("AppSettingValue");

string string_Local = "1B4D3A3C8F63DBE";
bool? areTheySame=null;
if (stringFromAppSetting == string_Local )
{
    areTheySame = true;
}
else
{
    areTheySame = false;
}

我还尝试了 stringFromAppSetting.Equals(string_Local).它仍然表明它们是不相等的.我使用notepad ++检查它们是否不同，但发现它们相同.

I also tried stringFromAppSetting.Equals(string_Local). It still shows they are not equal. I used notepad++ to check if they are different but I found that they are same.

有人可以提出可能的原因吗?

Can somebody please suggest the possible cause.

推荐答案

谢谢大家的回应.出于某种原因，当从appsettings.json文件中接收到字符串时，存在很多隐藏字符.在添加了删除隐藏字符的逻辑之后，它就像一种魅力....

Thank you all for your response. For some reason, lot of hidden characters were present when string was received from appsettings.json file.After adding a logic to remove hidden character, it worked like a charm....

从字符串内部删除隐藏字符
