我创建了一个先进的功能来发送基础上，通过answer proposed Mjolinor电子邮件。但是，我接受HTML代码块时遇到困难。这是抱怨System.String格式，不能转换为System.Management.Automation.SwitchParameter。PowerShell的发送，MAILMESSAGE BodyAsHTML错误类型
对于我的HTML代码我使用的是这里的字符串，使用时像Send-MailMessage -BodyAsHtml $HTML但不是当我尝试它，如下工作正常。我似乎无法弄清楚如何转换它，所以它的工作。
错误：
An error occurred while enumerating through a collection: Collection was modified; enumeration operation may not execute..
At S:\Test.ps1:168 char:9
+ $EmailParams.keys | Where {$EmailParams.$_ -eq $null} | foreach {$EmailP ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidOperation: (System.Collecti...tableEnumerator:HashtableEnumerator) [], RuntimeException
+ FullyQualifiedErrorId : BadEnumeration
Failed to send email to [email protected] due to: Cannot convert 'System.String' to the type 'System.Management.Automation.SwitchParameter' required by parameter 'BodyAsHtml'.
代码：
$HTML = @"
<!DOCTYPE html>
<html><head><style type="text/css">
body {font-family:verdana;background-color:white;}
h1 {background-color:black;color:white;margin-bottom:5px;}
h2 {background-color:lightGrey;margin-top:5px;}
h3 {margin-left:10px;font-size: 14px;}
p {font-size: 14px;margin-left:10px;}
p.italic {font-style: italic;font-size: 12px;}
table, td, th {font-size: 14px;border-collapse: collapse; border: 1px lightGrey; padding: 3px; text-align: left; padding-right:10px;}
li {font-size: 14px;}
base {target="_blank"}
</style></head><body>
<h1> $(if(!$ScriptName){"Test"}else{$ScriptName})</h1>
<h2> The following has been reported:</h2>
$Messages
</body></html>
"@
$EmailParams = @{
To = $To
Cc = $Cc
From = $From
Subject = $Subject
BodyAsHtml = $HTML
Priority = $Priority
SMTPServer = $SMTPserver
Attachments = $Attachment
ErrorAction = 'Stop'
}
$EmailParams.keys | Where {$EmailParams.$_ -eq $null} | foreach {$EmailParams.Remove($_)}
Try { Send-MailMessage @EmailParams }
Catch { "Failed to send email to $($To) due to: $_" }
Finally {}
This person有类似的问题，但这只是来一个System.String为-Body。
谢谢您的帮助。
有两件事情错在这里：
BodyAsHtml是一个布尔（$True），所以你需要使用Body提供您的HTML代码。- 你不能立即从哈希表中删除的东西。所以你需要2个
foreach循环。
完整的答案：
$HTML = @"
<!DOCTYPE html>
<html><head><style type="text/css">
body {font-family:verdana;background-color:white;}
h1 {background-color:black;color:white;margin-bottom:5px;}
h2 {background-color:lightGrey;margin-top:5px;}
h3 {margin-left:10px;font-size: 14px;}
p {font-size: 14px;margin-left:10px;}
p.italic {font-style: italic;font-size: 12px;}
table, td, th {font-size: 14px;border-collapse: collapse; border: 1px lightGrey; padding: 3px; text-align: left; padding-right:10px;}
li {font-size: 14px;}
base {target="_blank"}
</style></head><body>
<h1> $(if(!$ScriptName){"Test"}else{$ScriptName})</h1>
<h2> The following has been reported:</h2>

$EmailParams = @{

感谢。我正在考虑直接从powershell发送电子邮件（使用HTML模板），这非常有帮助。我想补充一点，你可以改进最终的解决方案。列表块可以完全删除并替换为这个，干杯：[System.Collections.ArrayList] $ EmailParams.keys | ？ {$ EmailParams。$ _ -eq $ null} | ％{$ EmailParams.Remove（$ _）} – Lorek 2016-12-20 00:47:21
