To expand on the answer provided by @Orion Edwards, this is how you would do fully from code-behind (no styles set). Basically create a custom class that inherits from Border which has its Child set to a TextBox. The example below assumes that you only want a single line and that the border is a child of a Canvas. Also assumes you would need to adjust the MaxLength property of the TextBox based on the width of the Border. The example below also sets the cursor of the Border to mimic a Textbox by setting it to the type 'IBeam'. A margin of '3' is set so that the TextBox isn't absolutely aligned to the left of the border.

double __dX = 20;
double __dY = 180;
double __dW = 500;
double __dH = 40;
int __iMaxLen = 100;

this.m_Z3r0_TextBox_Description = new CZ3r0_TextBox(__dX, __dY, __dW, __dH, __iMaxLen, TextAlignment.Left);
this.Children.Add(this.m_Z3r0_TextBox_Description);

实现您在这里谈论的内容的最佳方法是创建一个支持VerticalContentAlignment的标签

然后，如果你真的需要一些标签不涵盖的TextBlock属性，如TextWrapping，你可以在你的标签内放置一个TextBlock

结果满足了你的需求，VerticalContentAlignment和textwrap

<Label
   VerticalContentAlignment="Center">
   <TextBlock
             TextWrapping="WrapWithOverflow">
             My text goes here!
   </TextBlock> 
<Label/>

只是为了好玩，试试这个XAML吧。它不是完美的，因为它不是一个“对齐”，但它允许你调整一个段落中的文本对齐。

<TextBlock>
    <TextBlock BaselineOffset="30">One</TextBlock>
    <TextBlock BaselineOffset="20">Two</TextBlock>  
    <Run>Three</Run>            
    <Run BaselineAlignment="Subscript">Four</Run>   
</TextBlock>

TextBlock不支持其内容的垂直对齐。如果你必须使用TextBlock，那么你必须对齐它与它的父。

然而，如果你可以使用标签代替(他们确实有非常相似的功能)，那么你可以定位文本内容:

<Label VerticalContentAlignment="Center" HorizontalContentAlignment="Center">
   I am centred text!
</Label>

默认情况下，标签将拉伸以填充其边界，这意味着标签的文本将居中。

我发现修改文本框的样式(即:controltemplate)，然后修改part_contentthost垂直对齐到中心将做的技巧

你可以使用标签而不是文本块。

<Label Content="Hello, World!">
    <Label.LayoutTransform>
        <RotateTransform Angle="270"/>
    </Label.LayoutTransform>
</Label>
