将自定义类的数组存储在设置文件中

我有一个类:
public class CustomClass
{
public string Columns;
public string Filter;
public string SourceDB;
public string SourceTable;
public string DestinationDB;
public string DestinationTable;
}
在用户设置中,我需要存储一个CustomClass数组。这是因为我需要用户能够在app.config文件中指定多个CustomClass。
您必须首先在项目设置文件中创建一个设置,将其命名为CustomClasses
。下一部分有点棘手,因为它涉及编辑Settings.Settings文件的XML:
<?xml version='1.0' encoding='utf-8'?>
<SettingsFile xmlns="http://schemas.microsoft.com/VisualStudio/2004/01/settings"
CurrentProfile="(Default)"
GeneratedClassNamespace="ConsoleApplication1.Properties"
GeneratedClassName="Settings">
<Profiles />
<Settings>
<Setting Name="CustomClasses"
GenerateDefaultValueInCode="false"
Type="System.Collections.Generic.List<ConsoleApplication1.CustomClass>"
Scope="User">
</Setting>
</Settings>
</SettingsFile>
如果您打开Settings.Designer.cs文件,您现在应该有:
[global::System.Configuration.UserScopedSettingAttribute()]
[global::System.Diagnostics.DebuggerNonUserCodeAttribute()]
public global::System.Collections.Generic
.List<ConsoleApplication1.CustomClass> CustomClasses {
get {
return ((global::System.Collections.Generic
.List<ConsoleApplication1.CustomClass>)(this["CustomClasses"]));
}
set {
this["CustomClasses"] = value;
}
}
您可以在应用程序中保存设置:
class Program
{
static void Main(string[] args)
{
Properties.Settings.Default.CustomClasses = new List<CustomClass>() {
new CustomClass(){Columns="columns1"},
new CustomClass(){Columns="columns2"},
new CustomClass(){Columns="columns3"},
new CustomClass(){Columns="columns4"}
};
Properties.Settings.Default.Save();
}
}
您可以在App.config中声明CustomClassSection,并在CustomClass实例的集合内声明。类似于:
<configuration>
<configSections>
<section name="CustomClassSection" type = "A type of class section " />
</configSections>
</configuration>
<CustomClassSection>
<CustomClass Columns="column1" Filter="filter1" SourceDB="sourcedb1" SourceTable="sourcetable1" DestinationDB="destdb1" DestinationTable="desttable1"/>
<CustomClass Columns="column2" Filter="filter2" SourceDB="sourcedb2" SourceTable="sourcetable2" DestinationDB="destdb2" DestinationTable="desttable2"/>
...
</CustomClassSection>
