如果你可以不使用文本包装，我认为用标签替换TextBlock是最简洁的方法。否则，从其他有效答案中选择一个。

<Label Content="Some Text" VerticalAlignment="Center"/>

  <TextBox AcceptsReturn="True" 
           TextWrapping="Wrap"  
           VerticalContentAlignment="Top" >
  </TextBox>

TextBlock不支持垂直文本对齐。

我通过用网格包装文本块并设置horizontalalign ="Stretch"和verticalalign ="Center"来解决这个问题。

是这样的:

<Grid>
    <TextBlock 
        HorizontalAlignment="Stretch"
        VerticalAlignment="Center"
        Text="Your text" />
</Grid>

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

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);
