我想存儲在一個自定義元素我的ASP.NET web.config文件中三個值,所以這是我的web.config:的ConfigurationSection - StringValidator失敗
<?xml version="1.0"?>
<configuration>
<configSections>
<section name="mySection" type="Foobar.MySection,Foobar" />
</configSections>
<mySection baseUri="https://blargh" sid="123" key="abc" />
<!-- etc, including <system.web> configuration -->
</configuration>
這是我的配置代碼:
namespace Foobar {
public class MySection : ConfigurationSection {
public MySection() {
}
[ConfigurationProperty("baseUri", IsRequired=true)]
[StringValidator(MinLength=1)]
public String BaseUri {
get { return (String)this["baseUri"]; }
set { this["baseUri"] = value; }
}
[ConfigurationProperty("sid", IsRequired=true)]
[StringValidator(MinLength=1)]
public String Sid {
get { return (String)this["sid"]; }
set { this["sid"] = value; }
}
[ConfigurationProperty("key", IsRequired=true)]
[StringValidator(MinLength=1)]
public String Key {
get { return (String)this["key"]; }
set { this["key"] = value; }
}
}
}
我使用此代碼加載它:
MySection section = ConfigurationManager.GetSection("mySection") as MySection;
String x = section.BaseUri;
然而,當我在ASP.NET運行我的代碼,我得到這個異常:
[ArgumentException: The string must be at least 1 characters long.]
System.Configuration.StringValidator.Validate(Object value) +679298
System.Configuration.ConfigurationProperty.Validate(Object value) +41
[ConfigurationErrorsException: The value for the property 'baseUri' is not valid. The error is: The string must be at least 1 characters long.]

System.Configuration.ConfigurationManager.GetSection(String sectionName) +78
<my code that calls GetSection>
爲什麼在我的web.config中設置格式正確的值時,StringValidator會失敗?我忽略了什麼?
對不起,那是一個錯字,當我抄我的web.config中的StackOverflow。我的實際web.config文件是格式良好的。 – Dai
甚至,我沒有期待這樣的聲譽的人這樣的錯誤;) –
我通過解決大量簡單的問題而不是幾個難題來獲得我的聲譽。這是我的祕密恥辱。 – Dai
