メソッドを使用すると問題が発生します X509Store.Certificates.Find
public static X509Certificate2 FromStore(StoreName storeName,
StoreLocation storeLocation, X509FindType findType, string findValue)
{
X509Store store = new X509Store(storeName, storeLocation);
store.Open(OpenFlags.ReadOnly);
try
{
//findValue = "7a6fa503ab57b81d6318a51ca265e739a51ce660"
var results = store.Certificates.Find(findType, findValue, true);
return results[0];
}
finally
{
store.Close();
}
}
この場合、Findメソッドは0の結果(results.Count == 0
)を返しますが、findValueを定数として指定すると、メソッドは証明書を検索します。
public static X509Certificate2 FromStore(StoreName storeName,
StoreLocation storeLocation, X509FindType findType, string findValue)
{
X509Store store = new X509Store(storeName, storeLocation);
store.Open(OpenFlags.ReadOnly);
try
{
//findValue= "7a6fa503ab57b81d6318a51ca265e739a51ce660"
var results = store.Certificates.Find(findType,
"7a6fa503ab57b81d6318a51ca265e739a51ce660", true);
return results[0];
}
finally
{
store.Close();
}
}
