How to get outer variable from .net core mvc view's function?-CodePudding

I create a variable and function in view, how to get outer variable inside function ?

@{
    var myUrl = "https://example.com";
    @functions{
        private string ReplaceDomain(string replaceStr)
        {
            // Can't resolve symbol `myUrl`
            return myUrl.Replace("ABC", replaceStr);
        }
    }
}

<div>
My view
@ReplaceDomain("HAPPY")
@ReplaceDomain("BIRTHE")
@ReplaceDomain("DAY")
</div>

Always show "Can't resolve symbol myUrl" in function.

Is there any way to get outer variable directly?

Not like following method (not get variable directly)

@{
    var myUrl = "https://example.com";
    @functions{
        private string ReplaceDomain(string myUrl, string replaceStr)
        {
            // Can't resolve symbol `myUrl`
            return myUrl.Replace("ABC", replaceStr);
        }
    }
}

<div>
My view
@ReplaceDomain(myUrl, "HAPPY")
@ReplaceDomain(myUrl, "BIRTHE")
@ReplaceDomain(myUrl, "DAY")
</div>

CodePudding user response：

You can directly define method in razor view, just change your code like below:

@{
    var myUrl = "https://example.com";
    string ReplaceDomain(string replaceStr)
    {
        return myUrl.Replace("ABC", replaceStr);
    }
    
}

<div>
    My view
    @ReplaceDomain("HAPPY")
    @ReplaceDomain("BIRTHE")
    @ReplaceDomain("DAY")
</div>
