错误：accessor must be more restrictive than the property or indexer 'Framework.OracleProvider.db'，如何解决？
提问于 2018-02-01 01:45:50
我有以下程序：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Data.Odbc;
namespace Framework
{
public class OracleProvider
{
private OdbcConnection db { get; private set; }
private String dbUsername = Settings.Default.Username;
private String dbPassword = Settings.Default.Password;
public OracleProvider()
{
connect();
}
public void connect()
{
db = new OdbcConnection("Driver={Microsoft ODBC for Oracle};Server=CTIR; UID="+dbUsername+";PWD="+dbPassword+";");
}
}
}现在我得到以下错误：
Error 11: The accessibility modifier of the 'Framework.OracleProvider.db.set' accessor must be more restrictive than the property or indexer 'Framework.OracleProvider.db'

这就是问题所在：
private OdbcConnection db { get; private set; }假设您确实希望getter和setter都是私有的，那么应该是：
private OdbcConnection db { get; set; }策划人是已经private，因为这是整个属性的可访问性。
或者，如果您希望getter是非私有的，而setter是私有的，则需要指定其他修饰符。
internal OdbcConnection db { get; set; }基本上，如果要在get;或set;它必须比其他情况下的限制更严格。

这个错误告诉所有的所需资料:
accessibility modifier ... accessor must be more restrictive than the property ...
private OdbcConnection db { // <- property as whole is "private"
get;
private set; // <- accessor (set) is explictly declared as "private"
}所以你可以
// property as a whole is "public", but "set" accessor is "private"
// and so the accessor is more restrictive than the property
public OdbcConnection db { // <- property as whole is "public"
get;
private set; // <- accessor is "private" (more restrictive than "public")
}或
private OdbcConnection db {
get;
set; // <- just don't declare accessor modifier
