是否可以从.Net Blazor Web应用程序访问本地用户证书存储？

Question

我无法在Web程序集（Blazor Web应用程序）中加载用户证书。 这是我的代码（经过修改的示例“ Blazor入门”）。

 ...added strings to _ViewImports.cshtml:
@using System.Security.Cryptography;
@using System.Security.Cryptography.X509Certificates;
@using System.Security;
...


@page "/counter"

<h1>Counter</h1>

<p>Current count: @currentCount</p>
<p>Cert Name: @cname</p>

<button class="btn btn-primary" onclick="@IncrementCount">Click me</button>

@functions {
int currentCount = 0;
string cname = "";
public X509Certificate2 UserCert;

void IncrementCount()
{
    currentCount++;
    UserCert = selectCert();
    cname = UserCert?.GetNameInfo(X509NameType.SimpleName, false);
}

public X509Certificate2 selectCert() 
{
    X509Certificate2 certSelected = null;
    try
    {
        X509Store x509Store = new X509Store("MY", StoreLocation.CurrentUser);
        x509Store.Open(OpenFlags.ReadOnly | OpenFlags.OpenExistingOnly);
        X509Certificate2Collection col = x509Store.Certificates;
        X509Certificate2Collection fcollection = (X509Certificate2Collection)col.Find(X509FindType.FindByTimeValid, DateTime.Now, false);
        if (fcollection.Count > 0)
        {
            certSelected = fcollection[0];
        }
        x509Store.Close();
    }
    catch (Exception ex)
    {
        cname = ex.Message;
    }
    return certSelected;
}

} 

但是它失败，并显示异常消息“ Store MY不存在”或smth。因此，我只想访问用户证书存储区以进行数字签名等。我该怎么办？谢谢。
